Cookie Policy
Effective date: April 9, 2026
HarborConvert uses cookies and similar browser storage technologies to keep you signed in, remember your preferences, and (for free-tier users) show relevant ads. This page explains exactly what we use and how to control it.
What are cookies?
Cookies are small text files stored in your browser by websites you visit. They allow sites to remember information between page loads and visits. “Similar technologies” include localStorage and sessionStorage — browser storage that works the same way but is not sent with every request.
Cookies we use
These cookies are required for the service to function. You cannot opt out without losing core functionality like staying signed in.
| Cookie | Set by | Purpose |
|---|---|---|
| sb-access-token | Supabase | Maintains your authenticated session |
| sb-refresh-token | Supabase | Renews your session without requiring re-login |
We store lightweight UI settings in your browser's localStorage (e.g., converter output quality settings). This data lives only on your device and is never sent to our servers. You can clear it at any time by clearing your browser's site data.
We may use privacy-respecting analytics to understand which converters are most popular and how the site is performing. Analytics data is aggregated and anonymized — no personally identifiable information is used. You can opt out by enabling “Do Not Track” in your browser or using a browser extension like uBlock Origin.
Free-tier users see ads served by Google AdSense. Google uses its own cookies to show ads that are relevant to your interests, based on your browsing activity across sites that use Google services. These cookies are set by Google, not by us, and are governed by Google's Privacy Policy.
To opt out of personalized ads: visit Google Ads Settings or the Digital Advertising Alliance opt-out. Upgrading to a Pro or Business plan removes all ads.
