Cookie & Local Storage Policy
Last updated: May 31, 2026
What are cookies?
Cookies are small text files that are stored on your device (computer, tablet, or smartphone) when you visit a website. They allow the website to recognize your device and remember certain information about your visit, such as your preferences and session status.
How does Fronti use cookies and local storage?
fronti.app uses cookies and browser storage technologies to operate securely, remember your preferences, and improve your experience. We do not use cookies for advertising purposes and we do not build advertising profiles.
Essential cookies (required)
These cookies are necessary for the basic functionality of fronti.app. They cannot be disabled without affecting the core features of the site.
| Cookie | Purpose | Duration |
|---|---|---|
| sb-*-auth-token | Supabase authentication session. Keeps you logged in across pages and visits. | 30 days |
| sb-*-auth-token-code-verifier | PKCE verification for secure magic link authentication. | Session |
Analytics cookies (optional)
We may use privacy-first analytics to understand how visitors interact with fronti.app. These analytics do not create advertising profiles, do not use third-party tracking cookies, and do not share data with advertising networks. If we implement analytics, we will update this section with specific details.
Local storage
In addition to cookies, fronti.app uses browser localStorage and sessionStorage to improve your experience. This data is stored only on your device and is never transmitted to our servers or third parties.
| Key | Type | Purpose |
|---|---|---|
| fronti_checklist_v1 | localStorage | Saves your checklist progress (which steps you've completed) so it persists between visits. |
| fronti_fx_rate | sessionStorage | Caches the current CHF/EUR exchange rate (from ECB/Frankfurter API) to avoid repeated API calls. Refreshes every 6 hours. |
Third-party cookies
fronti.app does not use third-party advertising cookies. We do not use Google Ads, Facebook Pixel, or any other advertising tracking technology.
When you click an affiliate link (e.g. Wise, Revolut), the destination website may set its own cookies according to its own cookie policy. Fronti has no control over these third-party cookies.
How to manage cookies
You can control and manage cookies through your browser settings. Most browsers allow you to:
- View and delete existing cookies
- Block all cookies or only third-party cookies
- Set preferences for certain websites
- Receive notifications when a cookie is set
Please note that blocking essential cookies will prevent you from staying logged in to your Fronti account.
To clear localStorage and sessionStorage data, you can use your browser's Developer Tools (typically accessible via F12 > Application > Storage).
Changes to this policy
We may update this cookie policy from time to time. The current version is always available at fronti.app/cookie-policy. Previous versions are replaced by the new version upon publication.
