Privacy, plainly stated

Study Archway Privacy Policy

Effective and last updated August 20, 2026

Archway is designed to help developers study system design without requiring an account. We minimize what leaves your device and explain the limited information used to operate subscriptions and improve lessons.

1. Who this policy covers

This policy applies to the Study Archway iPhone app and Study Archway’s public support and privacy pages. “Study Archway,” “we,” and “us” refer to the developer and operator of the Study Archway app.

2. Information stored on your device

Archway stores your onboarding assessment result, primary learning goal, study progress, lesson-answer state, saved lessons and theory notes, practice scores, preferences, notification settings, and cached subscription-access status locally on your device. Scratchpad notes also remain on your device.

This information supports your study experience. Archway does not currently require an account, and this local study information is not sent to Archway’s servers.

3. Optional lesson feedback

When you choose to send lesson feedback, Archway sends the following information to Supabase:

  • Lesson and module identifiers
  • Your Helpful or Needs work rating
  • Selected reason tags
  • Any optional written comment you provide
  • The Archway app version and submission time

Archway does not add your name, email address, account identifier, or device identifier to a lesson-feedback submission. We use feedback to evaluate and improve lesson quality, and we do not link it to an account or device identifier.

4. Connection information

Supabase and network providers necessarily receive connection information, such as an IP address and request metadata, to deliver, secure, and operate the feedback service. Archway does not store an IP address in the lesson-feedback record or use connection information to identify you, advertise to you, or track you.

5. Subscriptions and Apple services

Subscriptions are processed by Apple through In-App Purchase. Archway receives verified entitlement information such as the purchased product identifier, subscription status, and expiration date. Archway does not receive your complete payment-card details.

Apple may separately process purchase, diagnostics, and App Store information under Apple’s own privacy policy. Restoring purchases asks Apple to synchronize transactions for the Apple Account signed in on the device.

6. How information is used

Archway uses information to provide the app, preserve local study progress, verify Pro access, respond to support or privacy requests, protect the service, and improve curriculum quality. We do not sell personal information, serve third-party advertising, or use information to track you across apps or websites.

7. Service providers and disclosure

Supabase hosts submitted lesson feedback and is required to protect it consistently with this policy and applicable law. Apple processes subscriptions and related platform services. We may disclose information when required by law or when reasonably necessary to protect users or the security and integrity of Archway.

8. Retention and deletion

Submitted lesson feedback is retained for up to 24 months and then deleted automatically, unless a longer period is required for security, fraud prevention, or legal compliance.

You can reset study progress from You → Settings. Deleting Archway removes locally stored app data, subject to device backups managed by Apple. Because feedback does not contain an account or device identifier, a feedback-deletion request should include enough detail to locate the submission, such as the lesson, approximate submission time, and comment text.

9. Your choices and rights

Lesson feedback is optional and is transmitted only after you choose a rating and tap Send feedback. You can manage notifications in Archway and iPhone Settings, and manage or cancel subscriptions through Apple. Depending on where you live, you may have additional access, correction, deletion, restriction, or objection rights.

10. Children’s privacy

Archway is intended for software developers and is not directed to children under 13. We do not knowingly collect personal information from children.

11. Changes to this policy

We may update this policy as Archway changes. The effective date above will be revised when material updates are published. If an update materially changes how information is used, we will provide notice appropriate to the change.
