Hypergryph Check-in Privacy Policy

Last updated: August 21, 2026

Hypergryph Check-in (“this extension”) is an unofficial browser extension for daily SKPort (Arknights: Endfield) check-in. It is not operated by, endorsed by, or affiliated with Hypergryph.

Single purpose: complete the signed-in user’s daily SKPort attendance (manually or on a schedule the user chooses). It does not collect browsing history from other sites.

1. Information we collect and store

• Attendance record: last successful check-in date
• Run log: up to 20 recent check-in result messages
• Settings: auto-run, check-in mode, theme, language
• Account link: character name, server, sk-game-role, SKPort profile image URL
• Session: the SKPort cred / ACCOUNT_TOKEN cookie already in the browser (not a password)
• Latest reward: summary of the last check-in reward

This information is stored only in this browser’s local storage (chrome.storage.local). The extension does not operate its own backend and does not send personal data to a developer server.

2. How the information is used

• Prevent duplicate daily check-in
• Show attendance progress and rewards
• Link an account for API check-in
• Apply the auto-run settings you chose

3. SKPort sign-in data

This extension does not collect or store SKPort passwords. In API mode it reads the SKPort session already stored in the browser. In fallback mode it opens the official check-in page and clicks the check-in control. Login, if required, happens on SKPort’s own page.

4. Why permissions are used

• storage: save attendance records, settings, and account info
• cookies: read SKPort/Gryphline session cookies for API check-in only
• alarms: schedule the daily auto check-in
• tabs: open or close the fallback check-in tab and info pages
• notifications: optional desktop alerts if you turn them on
• host_permissions: only game.skport.com, www.skport.com, zonai.skport.com, as.gryphline.com, and www.gryphline.com

5. Deleting data

Removing the extension deletes its locally stored data. No copy is kept on a developer server.

6. Third parties

This extension does not sell, rent, or share user data with third parties. Check-in requests go only to the SKPort/Gryphline servers you already signed in to.

7. Limited Use

Information this extension accesses is used only for its single purpose (daily SKPort check-in) and related operation (error display and retries). It is not used or sold for ads, credit scoring, or data brokerage. Use of this data follows the Chrome Web Store User Data Policy, including the Limited Use requirements.

8. Disclaimer

In-game assets and trademarks belong to Hypergryph. This extension is not affiliated with Hypergryph.

9. Contact
