Privacy Policy

Last Updated: 12 June 2026

This Privacy Policy explains how SubKeep ("SubKeep", "we", "us", or "our") handles information through the SubKeep browser extension ("Extension") and the SubKeep website ("Website").

The Extension is designed to keep Google Keep data and SubKeep configuration local to your browser. The Website separately uses limited third-party services for feedback, release updates, analytics, and voluntary support payments.

1. The SubKeep Extension

Local extension data

The Extension uses the browser-provided chrome.storage.local API to store data needed for its features. This may include:

  • Folder and label configuration created within the Extension;
  • Selected Google Keep label identifiers;
  • Nested label relationships;
  • User interface state;
  • Account-scoped Extension settings; and
  • A randomly generated Extension client identifier used only in hashed form for error reporting when that reporting is enabled.

This data remains in your browser profile and is not stored on servers operated by us. Uninstalling the Extension may cause the browser to remove it.

Interaction with Google Keep

The Extension interacts with the Google Keep interface within your authenticated browser session. It does not request access to your Google account through Google APIs, intercept network traffic, or store copies of your Google Keep notes on servers operated by us.

Optional error reporting

Some production builds may use Sentry to receive sampled technical error reports. If enabled, a report may include:

  • Error messages and stack traces;
  • Extension version and runtime environment;
  • The part of the Extension or command associated with the error; and
  • A one-way hash of a randomly generated local client identifier.

The Extension is configured to remove request and user objects before sending an event and is not intended to send Google account details, note content, or label names. Error reporting remains disabled in builds that do not include a Sentry connection setting.

Sentry processes this information under its Privacy Policy.

2. Website Feedback and Release Updates

When you use the Website form, we collect the information you choose to provide:

  • Your email address;
  • Your feedback or message, if provided; and
  • Whether you explicitly requested SubKeep release updates.

The form requires either a message, a request for release updates, or both.

Feedback

We use your email address and message to review your feedback, respond when appropriate, improve SubKeep, and prevent abuse. Form submissions are processed and stored by Formspree under its Privacy Policy.

Release updates

Release updates are optional. Sending feedback does not subscribe you automatically. We add your email address to a release-update list only when you select the release-updates checkbox.

Formspree records your selection with the form submission. We currently maintain the release-update list manually and use it only to send occasional SubKeep release announcements. You may withdraw your request at any time by contacting us or replying to a release email.

3. Website Analytics

The Website uses Vercel Analytics to understand aggregate Website usage and improve the Website. Vercel may process limited technical and interaction information needed to provide this service. We do not use Website analytics to access Google Keep content or Extension data.

Vercel processes this information under its Privacy Notice.

4. Voluntary Support Payments

The Website links to a Stripe-hosted page for voluntary financial support. Payment and transaction information entered there is collected and processed by Stripe, not by the Extension. Stripe may provide us with limited transaction details needed to record and administer the payment.

Stripe processes payment information under its Privacy Policy.

5. Cookies and Similar Technologies

The Extension does not use advertising cookies. The Website and its service providers may use cookies or similar technologies where needed to operate their services, secure submissions, process payments, or measure Website usage. You can control cookies through your browser settings, although blocking them may affect some third-party features.

6. How We Use and Share Information

We use information only for the purposes described in this Policy, including:

  • Operating and improving SubKeep;
  • Responding to feedback and support requests;
  • Sending release updates when you consent;
  • Diagnosing technical errors;
  • Understanding aggregate Website usage;
  • Processing voluntary support payments; and
  • Protecting the Website and forms from spam or abuse.

We do not sell your personal information. We share information with service providers only as needed for the services described above, or when required by law, necessary to protect legal rights, or needed to prevent harm or abuse.

7. Retention and Security

Locally stored Extension data remains in your browser until you remove it, reset the Extension, or uninstall the Extension.

Website submissions, error reports, subscriber records, analytics information, and transaction records are retained only for as long as reasonably needed for the purposes described in this Policy, legal compliance, security, and dispute resolution. Third-party providers may apply their own retention periods.

We use reasonable measures to protect information, but no method of transmission or storage is completely secure.

8. Your Choices and Rights

Depending on where you live, you may have rights to request access to, correction of, or deletion of your personal information, or to object to or restrict certain processing.

You can:

  • Leave the release-updates checkbox unchecked and still send feedback;
  • Opt out by replying to a release email or contacting us;
  • Ask us to remove a feedback submission or subscriber record; and
  • Disable or remove the Extension to stop its local operation.

To make a privacy request, contact us using the details below. We may need to verify your request.

9. Children’s Privacy

SubKeep is not intended for children under the age of 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through the Website, contact us so we can address it.

10. International Processing

Our service providers may process information in countries other than your own, including the United States. Privacy laws in those countries may differ from those where you live. Each provider is responsible for the safeguards described in its own privacy documentation.

11. Changes to This Privacy Policy

We may update this Privacy Policy when SubKeep or its supporting services change. Updates will be posted on this page with a revised "Last Updated" date.
