Cookie Policy
What cookies MentionFox uses and why
Last updated: April 2026
Our Approach to Cookies
MentionFox uses a minimal cookie approach. We use only the cookies strictly necessary for the service to function. We do not use advertising cookies, tracking pixels, or third-party marketing trackers of any kind.
Because we only use essential cookies, we do not display a cookie consent banner. Under GDPR Article 5(3) and the ePrivacy Directive, strictly necessary cookies are exempt from consent requirements.
Cookies We Use
| Cookie / Storage | Purpose | Type | Duration |
|---|---|---|---|
sb-*-auth-token | Supabase authentication session. Keeps you logged in across pages and browser sessions. | Essential (localStorage) | Until logout or token expiry |
sb-*-auth-token-code-verifier | PKCE code verifier for secure OAuth authentication flows. | Essential (localStorage) | Temporary (during auth flow only) |
These are stored in your browser's localStorage, not as traditional HTTP cookies. They are accessible only by MentionFox and cannot be read by any other website.
Analytics
We use Umami, a privacy-friendly, open-source analytics tool. Umami is notable because it:
- Does not use cookies — no cookie consent banner is needed.
- Does not collect personally identifiable information — no IP addresses, device fingerprints, or cross-site tracking.
- Does not share data with third parties — analytics data stays within our Umami instance.
- Is GDPR compliant by design — collects only aggregate page view and event data.
What We Do NOT Use
- No Google Analytics — we do not use Google Analytics, Google Tag Manager, or any Google tracking services.
- No Facebook Pixel — we do not use Meta/Facebook tracking pixels or conversion APIs.
- No advertising cookies — we do not serve ads and do not use any ad-related tracking.
- No cross-site tracking — we do not track your browsing activity on other websites.
- No fingerprinting — we do not use browser fingerprinting techniques to identify users.
Third-Party Cookies
The only third-party service that may set cookies when you use MentionFox is Stripe (our payment processor), and only when you interact with payment forms. Stripe sets cookies necessary for fraud prevention and payment processing. See Stripe's cookie policy for details.
How to Control Cookies
You can clear MentionFox's localStorage data at any time through your browser's developer tools or settings. Note that clearing authentication tokens will log you out of MentionFox.
Most browsers allow you to block or delete cookies and localStorage through their privacy settings. Refer to your browser's documentation for instructions.
