Privacy
Effective date: 7 November 2026. TrailWrite is a Chrome extension and this website. This page says what we collect, what we do not, and what you can ask us to do.
What stays on your device
The extension stores your settings, snippets, run history and pace profile locally in your browser. TrailWrite does not receive the text you type or the documents you work in. Optional writing notes use Chrome's built-in on-device AI, so that text is processed on your computer. The screen and page share features copy their result to your clipboard only; nothing is uploaded.
What we collect if you sign in
Signing in is optional. If you sign in with Google or email through Firebase Authentication, we store your email address and a user ID. If you turn on sync, your settings are saved as JSON in Firestore under your own user ID, and our access rules let only you read or write them. This website itself has no forms, no analytics and no tracking.
What we do not do
We do not sell or share your data, show ads, or build advertising profiles. We use your data only to run sign-in and sync, and for nothing else.
The use of information received from Google APIs and Chrome will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements. Our use of information complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
Retention and deletion
Local data lives until you clear it or remove the extension. Synced data and your account stay until you ask us to delete them. To delete your account, sign out of the extension, then email trailwrite.help@gmail.com from the address you signed in with. We will delete your account and synced data.
Children
TrailWrite is not directed at children under 13 and we do not knowingly collect their data (COPPA). If you think a child has signed in, email us and we will delete the account.
Your rights
Under GDPR, CCPA and similar laws you can ask to access, correct, export or delete your data, and to object to processing. We do not sell personal information. Email us to use any of these rights.

We will post changes to this page and update the effective date.
