Cookie policy
Last updated: July 2026
1. What are cookies?
Cookies are small text files that websites store on the user's device. Their purpose is to remember information about the visit to make the service easier to use.
2. Types of cookies we use
Xtalvi uses technical or strictly necessary cookies for the service to work. In addition, the free plan of the app shows ads via Google AdSense, which may use advertising cookies to show personalised ads. We do not use our own analytics or tracking cookies.
3. Cookie details
| Cookie/Token | Origin | Purpose | Duration | Type |
|---|---|---|---|---|
| JWT session token | Xtalvi | Maintain the authenticated user session | 30 days | Technical |
| Long-lived JWT token | Xtalvi | Allow access from the native iOS shortcut without re-authenticating | Persistent (revocable) | Technical |
| Language preferences | Xtalvi | Remember the selected language (ES, EN, CA) | Persistent | Technical |
| Google OAuth authentication cookies | Google LLC | Manage the Google sign-in flow. Only activated if the user chooses this option | Session | Technical |
| Google AdSense advertising cookies | Google LLC | Show and personalise ads on the free plan. Only active on the free version of the app and with the user's consent | Up to 13 months | Advertising |
4. Google OAuth and third-party data
If the user signs in with Google, the process is managed by Google LLC via OAuth 2.0. Google may set its own cookies in accordance with its policy at policies.google.com/privacy. Xtalvi only receives the user's identifier and email address.
5. Consent for ads (AdSense)
On the free version of the app, before showing personalised ads we ask for your consent through Google's native consent message (Google User Messaging Platform). You can accept or decline ad personalisation; if you decline, you'll still see ads, just not personalised based on your activity. Xtalvi's own technical cookies (session, language) are strictly necessary for the service to work, so no prior consent is required for those.
6. How to manage or delete cookies?
Cookies can be managed from your browser settings. Disabling technical cookies may prevent the service from working correctly. Instructions by browser:
7. Amendments
The owner reserves the right to amend this policy to adapt it to legislative or service changes.
