Privacy Policy

Last updated: June 2025  ·  Applies to Capy: Student Study Suite (Chrome Extension)

What data Capy collects

Capy stores the following data locally in your browser using Chrome's storage API. This data never leaves your device unless explicitly stated below.

• Study content — notes, flashcards, tasks, URL folders, and highlights you create
• Study activity — timer sessions, XP, streak days, and books earned
• Settings — theme preferences, display filters, widget toggles, active accessories
• A randomly generated UUID — created on first install, used only to associate your email with your account if you subscribe. It contains no personal information

Email address (optional)

If you choose to subscribe to Capy updates via the Settings panel, your email address and UUID are sent to a Cloudflare Worker and stored in a private database. This is used only to send product updates, new feature announcements, and occasional study tips.

• We will never sell or share your email with third parties
• You can unsubscribe at any time by emailing hello@niallcodes.com
• Subscription is entirely optional — Capy works fully without it

Pro subscription payments

If you upgrade to Capy Pro, payments are processed by Stripe. We never see or store your card details. Stripe's privacy policy applies to payment data. Upon successful payment, a license key is issued to your extension to unlock Pro features.

Web highlighting

Text you highlight on webpages is stored locally in your browser, indexed by page URL. This data never leaves your device and is not accessible to website owners or third parties.

Permissions Capy uses

• Storage — to save your notes, flashcards, tasks, and settings locally

• Notifications — to show a desktop notification when your timer completes
• Active tab / Scripting — to inject the highlight toolbar and floating widgets on pages you visit
• Declarative Net Request — to block distracting sites during Lock In mode
• Offscreen — to play the timer completion chime when the popup is closed

Third-party services

Data retention and deletion

All local study data can be deleted at any time by removing the Capy extension from Chrome, or by using the "Reset all data" option in the developer panel. Removing the extension clears all locally stored notes, flashcards, tasks, and settings from your device permanently.

If you have subscribed to email updates and wish to have your email removed from our records, email us at hello@niallcodes.com and we will delete it within 7 days.

Children's privacy

Capy is intended for students aged 13 and over. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information, please contact us and we will delete it promptly.

Changes to this policy

We may update this policy as Capy evolves. Significant changes will be noted in the extension's update notes. Continued use of Capy after changes constitutes acceptance of the updated policy.
