Cookie Policy

The marketing site you’re reading now doesn’t use analytics cookies, advertising pixels or cross-site trackers. Our free tools run entirely in your browser — your files and figures are processed on your device and never uploaded.

We use local storage (not cookies) for small conveniences only, such as remembering your light/dark theme preference. This data stays in your browser and is never sent to us.

When you sign in to the app, we use essential cookies and browser storage to keep your session active and secure (via our authentication provider, Supabase). These are strictly necessary to provide the service — the app cannot work without them — so consent is not required for them under GDPR/ePrivacy rules.

If you upgrade to a paid plan, our payment processor Stripe may set cookies on its own checkout pages for fraud prevention and to process your payment. See Stripe’s cookie policy.

You can clear or block cookies and site data in your browser settings at any time. Blocking essential cookies will prevent you from staying signed in to the app; this marketing site will keep working normally.

If we ever introduce analytics or any non-essential cookies, we’ll update this page and ask for your consent first where the law requires it. Questions? Email privacy@billingotter.com or read our Privacy Policy.
