1. What cookies are
Cookies are small files stored on your device. We use them (and similar browser storage) to keep you signed in, remember your preferences, and — only with your consent — to understand usage and show advertising.
2. Your control
We do not set analytical or advertising cookies until you consent. You chose your preferences when you first visited; you can change them any time:
3. Categories we use
| Category | Purpose | Consent | Typical duration |
|---|---|---|---|
| Essential | Sign-in session, security, and consent record. The service can’t run without these. | Always on | Session – 12 months |
| Analytical | Anonymous, aggregated usage insights to improve the product. | Optional | Up to 12 months |
| Advertising | Google AdSense on the free tier (never shown to premium members). | Optional | Up to 13 months |
4. Third-party cookies
- Stripe — fraud prevention and secure checkout (set during payment).
- Google AdSense — advertising, only if you accept advertising cookies.
- Supabase — authentication/session cookies (essential).
These third parties set their own cookies under their own policies. See our Privacy Policy for the full list of processors.
5. Managing cookies in your browser
You can also block or delete cookies through your browser settings. Blocking essential cookies may stop parts of the service from working. Guidance is available in the help pages of Chrome, Firefox, Safari, and Edge.
