Key commitments at a glance

Your password is never stored in plaintext. It is hashed using a one-way cryptographic algorithm at the moment of entry. Only the hash is stored; the plaintext is immediately discarded and is irrecoverable by anyone, including us.

Files are never stored on our servers. Attachments are processed in memory only for the duration of your request, then permanently discarded.

Prompt text is retained for a maximum of 7 days after processing, solely for service continuity and critical error debugging, then automatically and irreversibly deleted.

We do not use your data to train any AI model, including Anthropic's Claude models and DeepSeek models, under any circumstance.

We do not sell, rent, or license your personal data to any third party. Data is shared only with the limited set of sub-processors described in Part 3.

You can request deletion of your data at any time by contacting us at support.coworker@gmail.com. We respond within 48 business hours.

Part 1 — Who we are and what we collect

9 sections

The Coworker AI Chrome extension, our website at coworkerai.com, and all related backend services (collectively, the "Services") are published and operated by Coworker AI Inc. ("Coworker AI," "we," "us," or "our"). Coworker AI Inc. is the data controller responsible for the personal data described in this Privacy Policy.

For all privacy-related inquiries, data access requests, or requests to exercise your rights, you may contact us at:

For the purposes of this Privacy Policy, the following terms have the meanings set out below:

This Privacy Policy applies to all Users of the Services, including all visitors to our website, individuals who join our beta waitlist, and users of the Chrome extension, regardless of their country of residence.

It covers all personal data collected by or on behalf of Coworker AI through:

  • The Chrome extension itself, including its backend API calls;
  • Our website and any forms hosted on it;
  • Our backend infrastructure and servers;
  • The third-party AI models and sub-processors described in Part 2.

This Privacy Policy does not govern the practices of third-party websites, applications, or services that may be linked to or accessible from our Services. You are encouraged to review the privacy policies of any third-party service you choose to interact with.

The following table lists every category of data you provide directly to us, the circumstances in which it is collected, and the purpose for which it is used.

The Coworker AI extension and its associated account system collect your password at two specific moments: when you create an account (sign-up) and when you authenticate into an existing account (sign-in). The following explains precisely how passwords are handled at each stage, in full compliance with the Chrome Web Store's requirements for transparency about the collection and processing of user credentials.

Sign-up

When you choose a password during account creation, it is immediately processed using a one-way cryptographic hashing algorithm (bcrypt or an equivalent industry-standard algorithm). This process transforms your plaintext password into a fixed-length hash value that cannot be reversed or decrypted by any party. The resulting hash — and only the hash — is stored in our database. The plaintext password is discarded immediately upon hashing and is never written to disk, logged, transmitted to any third party, or accessible to any member of our team.

Sign-in

When you sign in, the password you enter is processed using the same cryptographic algorithm. The resulting hash is compared against the stored hash associated with your account. If the two values match, access is granted. The plaintext password you enter at sign-in is never stored, logged, or transmitted anywhere — only the hash comparison is performed, and only the stored hash persists.

Why this architecture matters

You are the only person who knows your password. Because we store only a one-way hash and never the plaintext, it is technically impossible for us — or for any party that might gain unauthorized access to our database — to retrieve or reconstruct your password. If you lose your password, we cannot recover it; you must reset it using the password-reset flow, which issues a new credential.

What we do not do with your password

  • We do not store your password in plaintext at any point in the sign-up or sign-in flow;
  • We do not transmit your plaintext password to our servers — hashing occurs client-side before any network transmission;
  • We do not share your password hash with any third party, including our AI inference providers (Anthropic and DeepSeek), our cloud hosting providers, or any other sub-processor;
  • We do not use your password or its hash for any purpose other than verifying your identity at sign-in.

The following data is collected automatically when you use the extension. All collection is strictly limited to what is necessary to deliver the feature in question and is never initiated without a corresponding action by you.

The extension is a task-automation agent. When you start a task, it may read page elements, enter text you provide or the AI generates, click buttons or links, and navigate across pages — but only on the site(s) required for that task, and only after you explicitly initiate it. The extension never acts on pages in the background, never reads pages you have not directed it to, and never collects or transmits any data without your action.

Our website collects the following categories of data automatically when you visit it:

  • Device and connection information: browser type and version, operating system, screen resolution, and the URL of the page you came from. Used for basic analytics and security.
  • General location data inferred from IP address: country and approximate region only; precise geolocation is never collected. Used for security monitoring and to determine the applicable language for the site.
  • Page views and navigation path: which pages of our site you visit and in what order. Used for aggregate analytics to improve the website.
  • Strictly necessary session cookies: described fully in Section 23 below.

We do not collect: passwords or credentials for third-party accounts (only your Coworker AI account password, handled exclusively as described in Section 4a); payment card numbers or banking information; precise geolocation coordinates; biometric identifiers; advertising identifiers (IDFA, GAID, or similar); browsing history on sites unrelated to an active task; social network profile data; or any data from pages you visit when you have not explicitly started a task on that page. We also do not collect personal data from children under 13 (see Section 14).

The extension declares the following permissions in its manifest. Each permission is strictly scoped to the functionality described below, and none is used to collect data beyond what is described in this Privacy Policy.

8.1 Remote code

Coworker AI does not execute remote code. All JavaScript run by the extension is bundled within the extension package as submitted to and reviewed by the Chrome Web Store. The extension does not load scripts from external URLs, does not evaluate dynamically fetched code via eval() or equivalent mechanisms, and does not use <script src="..."> tags pointing to third-party servers. Network requests made by the extension are limited to transmitting your request data to our backend servers and to the AI providers listed in Part 2, and receiving their text responses — no executable code is returned to the extension through these channels.

Part 2 — How we process your data

6 sections

We process your data solely for the following purposes. We do not process personal data for any purpose other than those listed below.

We do not process your data for advertising, behavioural profiling, resale, data brokerage, or enrichment of any third-party database. We do not use your prompts, files, tab content, or page interaction data to train, fine-tune, evaluate, or improve any AI model — ours or any third party's.

To generate responses to your prompts and to carry out the actions you request, Coworker AI transmits the relevant prompt text, and any file or tab content you have submitted, to one or more third-party large language model ("LLM") providers. These providers process your data on our behalf as our sub-processors. We currently use the following AI model providers:

The choice of which provider handles a specific request may depend on: the feature you are using; your settings or model preferences; internal routing logic; or real-time availability and reliability considerations. The same protections described in this Privacy Policy apply regardless of which provider handles a given request.

We may add, remove, or change AI model providers as the Services evolve. Where such a change is material, we will update this section and notify you in accordance with Section 26.

The following rules govern how both Anthropic and DeepSeek handle data we transmit to them on your behalf:

  • No training on your data: Your prompts, attached files, and tab content are sent to these providers strictly to generate a response to your specific request. They are not used by us, or by the providers under our agreements with them, to train, fine-tune, benchmark, or evaluate any AI model.
  • Sub-processor relationship: Both providers act as our sub-processors, meaning they process your data solely on our instructions and may not use it for their own purposes beyond generating the requested response.
  • Strict data minimization: We transmit only the minimum data required to generate a response: the content of the prompt, file, or page you have chosen to submit for that specific request. We never transmit your account email address, password hash, payment details, browsing history unrelated to the task, or any other personal data not required to fulfil the specific request.
  • Subject to our retention limits: Data transmitted to these providers is subject to the retention periods described in Section 16 of this policy.
  • Cross-border processing: Both providers may process data on servers located in the United States and potentially other countries. See Section 18 on international data transfers.
  • Authentication tokens and passwords never shared: Your Coworker AI authentication token and password hash are shared only with our own backend servers. They are never transmitted to any AI provider.

In summary: whichever model handles your request — Anthropic's Claude or a DeepSeek model — it receives only what you explicitly submit for that request, is contractually prohibited from training on your data, and does not retain it beyond the periods described in this policy. Your password hash is never shared with any AI provider under any circumstances.

Where the General Data Protection Regulation (GDPR), the UK GDPR, or equivalent Swiss data protection law applies to the processing of your personal data, we rely on the following legal bases:

The Services use AI models (described in Section 10) to generate responses to your prompts. These AI-generated outputs are tools to assist you in completing tasks; they do not constitute automated decisions that produce legal effects or similarly significant effects concerning you.

We do not use your personal data to make decisions about you that produce legal or similarly significant effects through automated means without human review. If this changes in the future, we will update this section and notify you accordingly.

The Services are not directed to, and are not intended for use by, individuals under the age of 13 (or the minimum age required in your jurisdiction to consent to data processing without parental approval, which may be higher — for example, 16 in certain EEA member states).

We do not knowingly collect personal data from children. If we become aware that we have inadvertently collected personal data from a child below the applicable minimum age, we will take immediate steps to delete that data. If you believe a child has provided us with personal data, please contact us at support.coworker@gmail.com and we will investigate and act promptly.

Part 3 — Sharing, retention & security

6 sections

We do not sell, rent, or license your personal data. We share data only with the recipients described below and only to the extent strictly necessary for the purpose stated. Every recipient category is listed; there are no other parties with whom we share personal data.

15.1 AI inference providers (sub-processors)

Who: Anthropic, Inc. and DeepSeek. What is shared: the text of your prompt and any attached file or tab content you have submitted for a specific request. What is never shared: your password, password hash, email address, or authentication token. Why: to generate a response or carry out the action you requested. How: transmitted via encrypted HTTPS API calls under a commercial data processing agreement. Neither provider uses your data to train its models, in accordance with the terms of our agreements with them.

15.2 Hosting and cloud infrastructure providers (sub-processors)

Who: Cloud infrastructure providers such as Amazon Web Services (AWS) or Google Cloud Platform (GCP). What is shared: prompt text and request metadata (as part of our backend processing), email addresses and password hashes (for account management), and technical and diagnostic logs. Why: to run our backend systems, store limited data in accordance with the retention schedule in Section 16, and deliver the Services. How: hosted under contracts that restrict these providers from using our data for any purpose other than providing cloud hosting services to us.

15.3 Error monitoring and diagnostic tools (sub-processors)

Who: Technical error-monitoring providers such as Sentry. What is shared: anonymized or pseudonymized crash reports and error traces, including limited technical context such as the extension version, browser type, and error message. Personally identifying information — including any credential-related data — is redacted from error reports wherever technically possible. Why: to identify, diagnose, and fix technical bugs.

15.4 Email delivery and customer support platforms (sub-processors)

Who: Email delivery service providers (for sending waitlist notifications and account emails) and, where applicable, customer support platforms. What is shared: your email address and the content of any support communication you initiate. Why: to deliver transactional emails and to manage support inquiries. How: under contracts that prohibit use of your data for purposes other than delivering the services to us.

15.5 Legal and safety disclosures

Who: Law enforcement agencies, courts, regulatory authorities, or other public bodies. What is shared: only the data required by the specific legal request. Why and when: we may disclose data if required to do so by a valid legal obligation, court order, subpoena, or equivalent lawful process; or where we reasonably believe in good faith that disclosure is necessary to protect our legal rights, property, or safety or those of our Users or the public. We will make reasonable efforts to notify affected Users of such requests where legally permitted to do so.

15.6 Business transfers

If Coworker AI Inc. is involved in a merger, acquisition, restructuring, asset sale, financing, or insolvency proceeding, personal data may be transferred to the acquiring or surviving entity as part of that transaction. Where such a transfer occurs, we will endeavor to notify affected Users before the transfer takes place, and will require the receiving entity to adhere to a privacy policy that provides at least equivalent protections to this one.

15.7 Aggregated and de-identified information

We may share aggregate, anonymized, or de-identified data — from which individual users cannot reasonably be identified — with third parties for purposes such as industry research, trend analysis, or service improvement reporting. Such data is not personal data and is not subject to this Privacy Policy.

Complete summary: your data may reach Anthropic and DeepSeek (AI providers, prompt content only — never passwords or hashes), our cloud hosting provider, error-monitoring tools, and email/support platforms. It is never shared with advertising networks, data brokers, or any unrelated third party, and is never sold under any circumstances.

17.1 Deleting local extension data

To delete data stored locally on your device by the extension (authentication token, preferences), uninstall the extension from Chrome by navigating to chrome://extensions and selecting "Remove." If Chrome prompts you, select "Clear extension data" to ensure all locally stored data is deleted.

17.2 Requesting deletion of server-side account data

To request deletion of your account and associated data held on our servers (including your email address, password hash, and any retained prompt text), contact us at support.coworker@gmail.com. We will verify your identity, process your request, and confirm deletion within 30 days of a valid, verified request.

17.3 Scope of deletion

Upon a verified deletion request, we will delete your email address, password hash, account data, and any retained prompt text associated with your account. We may retain certain data beyond your request where a legal obligation, unresolved dispute, or fraud prevention requirement requires it, and will notify you of any such retention.

Coworker AI is incorporated and operates in the United States. Our service providers, including Anthropic, DeepSeek, and our cloud hosting providers, may process data on servers located in the United States and, in some cases, in other countries. If you are accessing the Services from the European Economic Area (EEA), the United Kingdom, Switzerland, or another jurisdiction with data transfer restrictions, your personal data may be transferred to a country that does not provide the same level of legal protection as your home jurisdiction.

Where we transfer personal data out of the EEA, UK, or Switzerland to a country not recognized as providing an adequate level of data protection, we rely on one or more of the following safeguards:

  • Standard Contractual Clauses (SCCs): We incorporate the European Commission's Standard Contractual Clauses into our agreements with relevant sub-processors.
  • Adequacy decisions: Where the European Commission or UK government has recognized a country as providing adequate protection, we may rely on that adequacy determination.
  • Other appropriate safeguards: In appropriate circumstances, we may rely on other recognized transfer mechanisms under applicable law.

You may request information about the transfer mechanisms we use by contacting us at support.coworker@gmail.com.

We implement technical and organizational security measures appropriate to the nature and sensitivity of the data we process. These measures include:

  • One-way password hashing: Passwords are never stored in plaintext. They are hashed using bcrypt or an equivalent industry-standard one-way algorithm immediately upon entry. The hash is stored; the plaintext is permanently discarded. This means that even in the event of a database breach, your actual password cannot be extracted or reconstructed.
  • Encryption in transit: All communications between the extension, our website, our backend servers, and our AI inference providers are encrypted using HTTPS/TLS. We do not transmit personal data over unencrypted channels.
  • Encryption at rest: Retained data stored on our servers (including email addresses, password hashes, and prompt text within the 7-day window) is encrypted at rest.
  • Minimal-retention architecture: Files are never stored on our servers. Prompt text is automatically and irreversibly deleted within 7 days. Diagnostic logs are deleted or anonymized within 30 days.
  • Access controls: Access to retained personal data is restricted to personnel with a legitimate operational need. We enforce role-based access controls and maintain access logs.
  • Sub-processor security: We contractually require all sub-processors to maintain security standards appropriate to the sensitivity of data transmitted to them.

No method of transmission over the internet or method of electronic storage is completely secure. While we take security seriously and implement the measures described above, we cannot guarantee the absolute security of your data.

In the event of a personal data breach that is likely to result in a risk to your rights and freedoms, we will:

  • Notify the relevant supervisory authority (where required under applicable law, including GDPR Article 33) within 72 hours of becoming aware of the breach, where feasible;
  • Notify affected Users without undue delay where the breach is likely to result in a high risk to their rights and freedoms, providing clear information about the nature of the breach, the data affected, the likely consequences, and the measures we have taken or propose to take;
  • Take immediate steps to contain and remediate the breach, and to prevent recurrence.

If you suspect your data may have been compromised, please contact us immediately at support.coworker@gmail.com.

Part 4 — Your rights & other disclosures

7 sections

Depending on the laws applicable in your jurisdiction, you may have some or all of the following rights with respect to your personal data.

To exercise any of the rights described in Section 21, please contact us at support.coworker@gmail.com. Please include sufficient information for us to identify you and the right(s) you wish to exercise.

We will verify your identity before acting on any request that involves personal data about you, to protect against unauthorized access or deletion of your data. We will respond within the timeframe required by applicable law and, in all cases, will acknowledge receipt of your request within 48 business hours.

We will not charge a fee for responding to your request unless the request is manifestly unfounded or excessive.

23.1 The Chrome extension

The Coworker AI Chrome extension does not use cookies. All persistent data required by the extension (authentication token, user preferences) is stored locally on your device using the chrome.storage.local API. This data is stored only on your device and is never transmitted to our servers except where explicitly required for authentication (the token only, not your preferences).

23.2 Our website

Our website uses only strictly necessary cookies required for the basic functionality and session security of the website. We do not use advertising or targeting cookies, third-party behavioural tracking cookies, social media tracking pixels, or analytics cookies that track individual users across sessions.

Some browsers offer a "Do Not Track" (DNT) signal that instructs websites not to track user activity across sites. Our website does not currently alter its behaviour in response to DNT signals, because no universally accepted technical standard for interpreting these signals has been adopted across the industry.

Regardless of DNT signals, we do not use cross-site tracking technologies, advertising cookies, or behavioural profiling on our website or through our extension, as stated in Section 9 and Section 23.

Coworker AI strictly does not execute remote code. All JavaScript executed by the extension is bundled within the extension package as reviewed and distributed by the Chrome Web Store. Specifically:

  • The extension does not load scripts from external URLs or third-party CDNs;
  • The extension does not use eval(), new Function(), or any equivalent mechanism to evaluate dynamically fetched strings as code;
  • The extension does not use <script src="..."> tags or equivalent patterns to inject external scripts;
  • Network requests made by the extension are limited to transmitting request data to our backend servers and to the AI providers listed in Part 2 over HTTPS, and receiving their text responses — no executable code is ever returned to the extension through these channels.

We may update this Privacy Policy from time to time to reflect changes to the Services, additions or removals of AI model providers, changes to applicable law, or changes to our data practices.

Where changes are material — including any change to the AI providers named in Section 10, any new category of data collection, or any new category of data recipient — we will notify you through: (a) an in-extension notice displayed when you next use the extension; (b) a prominent notice on our website; or (c) an email to the address associated with your account, where you have provided one.

Your continued use of the Services after a revised policy becomes effective constitutes your acceptance of the updated terms. If you do not agree with the revised policy, you must discontinue use of the Services.

For any question, concern, or request relating to this Privacy Policy, or to exercise any of the rights described in Section 21, please contact us using the details below. We aim to acknowledge all privacy-related communications within 48 business hours.
