This is the privacy policy for Filmina (filmina.app). The short version: we don't see your video, we don't track your browsing, and we hold the bare minimum data needed to honor a Pro license.
1. What runs locally
All video rendering — color presets, effects, tuning — happens inside your browser using WebGL or CSS+SVG filters. Filmina never uploads, copies, or transmits the contents of any video, image, or page you view.
2. What we collect
The extension stores the following locally on your device:
- Your current preset, tune values, and per-site settings (Chrome
storage.local) - Your saved custom looks
- Your appearance preferences and pipeline mode
- Your Pro license key and activation id, if you have one
None of it leaves your device, except your license key, which is checked as described in section 3. Uninstalling Filmina deletes all of it.
3. What we receive from Polar
When you purchase a Pro plan, Polar.sh handles checkout and billing. We receive a license key and a customer id back from Polar. We never see your card number, email, or billing address — those stay with Polar. Once a day the extension sends your license key to Polar and to filmina.app to confirm your plan (filmina.app asks Polar whether it's a subscription or Lifetime). When you click Manage plan in the popup, filmina.app uses the same key to open Polar's customer portal for you.
4. What we don't do
- No analytics or telemetry — we don't use Mixpanel, Amplitude, Sentry, or anything similar in the extension.
- No advertising — we don't sell or share any data with advertisers.
- No fingerprinting — the extension does not generate or transmit any device-identifying data.
- No content scraping — on the pages you visit, Filmina looks only for
<video>elements and the page's media artwork (to show a preview in the popup), and sends nothing from the page anywhere.
5. Permissions and requests
The extension asks for:
- storage — to keep your settings, looks and license on your device
- tabs — to know which site the current tab is on (for per-site settings), send your changes to its video, and open checkout pages
- alarms — to schedule the daily license check and the look updates
- access to filmina.app — for those updates and the license check
It also runs on the pages you visit, because a video can be on any site. There it only finds the video and draws on it.
The extension makes three kinds of request, all from the extension itself, never from the pages you visit:
- At most every six hours, it downloads look, effect and pricing updates (plain data files) from filmina.app.
- With Pro, it checks your license key with Polar and filmina.app once a day.
- When you uninstall, your browser opens filmina.app/uninstall, where you can tell us why if you like.
None of these include what you watch or which sites you visit.
6. The website
filmina.app has no analytics, ads or tracking cookies. If you write to us through the support or uninstall forms, your message, and your email if you give it, go to our support inbox and are used only to reply.
7. Data retention & deletion
Local data is removed when you uninstall the extension. To delete your Polar account and license records, contact privacy@filmina.app or use the account-deletion controls in the Polar customer portal.
