Privacy Policy

Last updated August 9, 2026

The short version

Highlightr saves the passages you choose, on your own device, by default. Nothing is shared publicly. If you create an account to sync across devices, your saves and your email are stored privately in Highlightr’s database, accessible only to you. Highlightr does not sell data, run ads, or track the pages you browse — only what you explicitly choose to save.

What Highlightr stores locally

By default, Highlightr requires no account. When you save a passage, the extension stores the excerpt, any note or topics you add, the source page’s URL/domain/title/author/ publish date where available, and the date you saved it — in your browser’s local storage only. This never leaves your device unless you sign in or export it yourself. Highlightr does not collect your general browsing history, only pages where you actively save something.

What happens if you sign in

Signing in is optional. If you create a Highlightr account, your email and password are sent to our authentication provider, Supabase, to create and verify your account — Highlightr does not store your password itself. Saves you make while signed in are also stored in Highlightr’s database (hosted on Supabase), tied to your account, so they’re reachable from this web app. Everything synced this way stays private — there is no public profile, feed, or sharing feature.

What Highlightr does not do

Does not sell or rent your data. Does not show ads or use advertising trackers. Does not build a profile of pages you visit beyond what you explicitly save. Does not share your saves publicly.

Your controls

Export everything as JSON or clear all local saves from the extension’s Settings at any time. Sign out to stop new saves from syncing. To delete your account and its data from our database entirely, contact us below.

Third parties

Highlightr uses Supabase to provide optional account sign-in and cross-device sync. Supabase processes this data on Highlightr’s behalf and does not use it for its own purposes. No other third party receives your data.

Children’s privacy

Highlightr is not directed at children under 13, and we do not knowingly collect data from them.

Changes to this policy

If this policy changes in a meaningful way, we’ll update the date at the top of this page.
