Cookie Policy
Effective date: 17 May 2026
1. What this policy covers
This Cookie Policy explains how RankTrade uses cookies and similar technologies on ranktrade.io. It supplements our Privacy Policy.
2. What is a cookie?
A cookie is a small text file placed on your device by a website. It lets the site recognise your device on future visits, remember preferences, and measure how the site is used. We also use related technologies such as local storage (data saved by your browser) to deliver the same kinds of functionality.
3. Categories of cookies we use
| Category | Purpose | Examples | Consent |
|---|---|---|---|
| Strictly necessary | Keep you signed in, secure forms against CSRF, balance load. | Supabase auth tokens, session cookies | Not required (essential) |
| Preferences | Remember UI state — theme, layout, favourite symbols, sound preferences. | ranktrade:symbol_favorites, ranktrade:sound_settings | Implied by use |
| Analytics | Understand which features are used and where users have trouble, so we can improve the product. | Aggregated, non-personally-identifiable | Consent where required |
| Marketing | Measure the effectiveness of campaigns and re-engage users who have not completed onboarding. | Only set if you opt in | Opt-in |
4. Third-party cookies
Some cookies are set by service providers acting on our behalf, such as our authentication and infrastructure provider. We do not allow these providers to use the data for their own purposes.
5. Managing your choices
- In-product controls. Where consent is required, we ask for it through a cookie notice. You can change your preferences at any time from your account settings.
- Browser settings. Most browsers let you block or delete cookies. Blocking strictly necessary cookies may break sign-in and other core features.
- Do Not Track. Standards in this area remain unsettled; we do not currently respond to DNT headers but we honour all valid opt-out signals from regional privacy frameworks where they apply to us.
6. Changes to this policy
We may update this Cookie Policy. Material changes will be announced in advance through the Service.
