Cookie Policy
What cookies we set, why, and how you stay in control.

What cookies are
Cookies are small text files a site stores on your device. We also use similar technologies such as localStorage. We group them into two buckets and only the strictly-necessary bucket runs without your consent.
Strictly necessary (always on)
These are required for the site to work, so they don't need consent:
- Authentication & security — set by our sign-in provider (Clerk) to keep you logged in and protect your account.
- Payments — set by Stripe during checkout to process your subscription securely and prevent fraud.
- Your consent choice — a small cookie (
tw_consent) that remembers whether you accepted optional cookies, so we don't ask again.
Optional (off until you accept)
These only run if you choose Accept all. If you choose Reject optional, they stay off:
- Product analytics — anonymous, aggregate usage data that helps us see which features get used and fix what's broken. We do not sell your data or use it for cross-site advertising.
Managing your choice
You decided when you first arrived. You can change or withdraw your choice any time — it's as easy to reject as to accept:
You can also block or delete cookies in your browser settings, though some strictly-necessary features (like staying signed in) may stop working.
Third parties
Cookies above are set by the providers we use to run the service: Clerk (auth), Stripe (payments), and our hosting/email infrastructure. Each processes data under its own policy. See our Privacy Policy for how we handle personal data and your rights under GDPR and CCPA/CPRA.
Changes
We'll update this page if our cookie use changes and bump the date above. Questions: reach us via the address in our Privacy Policy.
