1. What this policy covers
Tycho uses a mix of browser technologies to keep the application working, remember user preferences, maintain session continuity, and support billing or product-state messaging. Some of these technologies are traditional cookies; others are browser storage mechanisms such as localStorage or sessionStorage.
2. How Tycho currently uses browser storage
| Category | Purpose | Examples in Tycho |
|---|---|---|
| Essential access and continuity | Keep the user in the intended public application flow and preserve short-lived product state during a session. | Launch-access marker, billing success banners, session continuity flags, short-lived cached region values. |
| User preferences | Remember choices so the app does not reset on every visit. | Theme, language, notification preference, cached billing currency, and similar settings. |
| Product performance | Reduce unnecessary repeated requests or preserve lightweight temporary cache state. | Short-lived cache keys and internal UI rotation state. |
| Authentication or infrastructure support | Allow Firebase and related infrastructure libraries to maintain sign-in or client state where needed. | Browser-managed tokens, SDK state, and session continuity used by Firebase or the Tycho frontend runtime. |
3. Essential vs non-essential technologies
Tycho's current public product flow primarily relies on essential storage that supports the service requested by the user. If PromSpace later introduces non-essential analytics, advertising, or personalization cookies, those should be controlled through an appropriate consent mechanism before they are activated.
4. Third-party services that may set or rely on browser storage
- Firebase / Google infrastructure for sign-in, client runtime, and application storage.
- Stripe during billing and checkout flows, subject to Stripe's own technology and privacy notices.
- Embedded libraries or browsers themselves where storage is needed to safely deliver product features requested by the user.
5. How users can control browser storage
- Users can clear cookies and browser storage through browser settings.
- Users can revoke notification permissions through browser or device settings.
- Blocking essential storage may prevent Tycho from working correctly.
6. Relationship to the Privacy Policy
This Cookies Policy should be read together with the Privacy Policy, which explains the broader processing of personal data in Tycho.
