Cookie Policy
Last updated: 29 May 2026
This Cookie Policy explains how SkyStudy uses cookies, local storage, service workers, and similar browser technologies. It should be read together with our Privacy Policy and Terms of Service.
1. Technologies We Use
- Essential cookies keep you signed in and protect authenticated sessions.
- Local storage stores preferences such as theme, reduced-motion choices, and practice resume state.
- IndexedDB stores encrypted offline question packs and pending offline answers on your device.
- Service workers and browser cache help the app shell load and support offline study.
- Privacy-focused analytics may be used only after consent where required.
2. Strictly Necessary Storage
Authentication, security, payment access checks, rate limiting, fraud prevention, and offline study storage are necessary for the Service to work. These technologies cannot be disabled from the app without breaking core functionality, but you can remove them from your browser settings.
3. Analytics
SkyStudy uses privacy-focused analytics to understand broad usage patterns and improve the Service. We do not use advertising cookies, cross-site tracking pixels, or data broker tags. Where consent is required, analytics runs only after consent and can be disabled later from the consent banner or account settings.
4. Offline Study Storage
If you download offline question packs, the questions and pending answer queue are stored locally in your browser using IndexedDB. Clearing browser data, using private browsing, or switching devices may remove this offline data. Pending answers sync to your account when you return online.
5. Third-Party Processors
Some cookies or local storage entries may be set by processors that provide authentication, hosting, payments, analytics, or security services, including Supabase, Stripe, Vercel, Upstash, and Plausible. We do not permit these processors to use SkyStudy data for advertising.
6. Managing Cookies and Storage
You can manage or remove cookies and local storage from your browser settings. Common controls include:
- Deleting site data for skystudy-related domains
- Blocking non-essential cookies in your browser
- Clearing IndexedDB and cache storage for this site
- Using the in-app offline settings page to remove downloaded question packs and pending answers
Removing essential storage may sign you out, remove offline packs, delete unsynced local answers, or reset preferences on that device.
7. Changes
We may update this policy when we add or remove browser storage technologies. Material changes will be reflected on this page and, where required, communicated through the app.
