Tennis Magic AI uses a small number of first-party cookies to keep you logged in, remember your language and count your visits as one person. We do not use third-party advertising cookies or cross-site trackers.
What we set
| Name | Purpose | Lifetime | Type |
|---|---|---|---|
| session | Keeps you logged in | 30 days | Strictly necessary |
| tm_lang | Remembers your language choice | 1 year | Preference |
| tm_vid | A random visitor id so your visits count as one person and the site can see what works | 2 years | Analytics, first party |
| tm_sid | A random id for the current visit | 1 day | Analytics, first party |
| dash_auth | Server-side flag that you finished login | Browser session | Strictly necessary |
What the site records
With those ids the site records the pages you open, the buttons you press, how long you stay on a page and how far you scroll, together with your IP address and browser type. We use it to see which parts of the site work and to keep it safe. We never sell it. Details are in the Privacy Policy.
Stripe
The Stripe checkout on the Go Pro page sets its own cookies to process the payment and prevent fraud, governed by Stripe's policy at stripe.com/privacy. We have no access to them.
How to turn them off
Clear cookies in your browser at any time. Without the session cookie you are logged out; without tm_lang the site uses your browser's language; without tm_vid the site simply counts you as a new visitor next time.
