Cookie Policy
Last updated: February 23, 2026
1. What Are Cookies
Cookies are small text files stored on your device when you visit a website. They help websites remember your preferences and provide essential functionality. Signalry uses cookies strictly for essential purposes required to operate the Service.
2. Cookies We Use
Signalry uses only essential cookies — we do not use advertising, analytics, or tracking cookies.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
| sb-*-auth-token | Supabase authentication session | Session / 1 year | Essential |
| sb-*-auth-token-code-verifier | PKCE OAuth flow verification | Session | Essential |
3. Why These Cookies Are Essential
The cookies listed above are strictly necessary for the Service to function. They enable:
- Authentication — Maintaining your login session so you don't have to sign in on every page
- Security — Protecting against cross-site request forgery (CSRF) and ensuring OAuth flows are secure
- Session integrity — Ensuring your requests are associated with your account
Without these cookies, core features like logging in and accessing your dashboard would not work.
4. Third-Party Cookies
Signalry does not set any third-party cookies. We do not use:
- Google Analytics or any analytics service
- Facebook Pixel or any advertising tracker
- Any social media tracking widgets
- Any remarketing or retargeting services
Third-party services we integrate with (Supabase, Cloudflare) may set their own essential cookies for security and functionality purposes. These are governed by their respective privacy policies.
5. Local Storage
In addition to cookies, Signalry uses browser local storage for:
- Authentication tokens — Supabase stores session tokens in local storage for client-side authentication
- UI preferences — Sidebar state and other interface preferences
Local storage data remains on your device and is not transmitted to our servers beyond what is necessary for authentication.
6. Managing Cookies
You can control 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 specific websites
Important: Disabling essential cookies will prevent you from logging in and using the Service.

7. Do Not Track
Signalry does not track users across websites and does not respond to Do Not Track (DNT) browser signals, as we do not engage in any cross-site tracking.
8. Changes to This Policy
We may update this Cookie Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
