Privacy Policy

Effective date: June 13, 2026 · Last updated: June 13, 2026

The short version

Vusk does not collect, store, or sell your personal information.

Syllabus photos are sent to our AI extraction API solely to extract dates — they are not stored after processing.

No analytics, no advertising, no tracking.

All study data stays on your device and in your personal iCloud.

1. Who we are

Vusk is a solo-developed iOS study planner app. This policy describes how the Vusk app ("the App," "we," "our") handles information when you use it.

Questions? Contact us at support@vusk.cc.

2. Information we access on your device

The App stores all data locally on your device using SwiftData. This includes:

Subjects, assignments, and exam dates you add or import
Weekly schedule slots you configure
Completed focus session records
App preferences (notification tone, language, app icon)

This data never leaves your device except as described below under iCloud and AI extraction.

3. Camera and photo library

The Import feature lets you photograph a course syllabus, schedule, or assignment sheet. When you do this:

The image (or the OCR text extracted from it) is sent to our backend API at api.vusk.cc for AI-powered date and assignment extraction.
The image or text is processed immediately and is not stored by our API or any third party after the response is returned.
Our backend forwards the content to OpenAI's API (GPT-4o) to perform the extraction. OpenAI's data handling is governed by OpenAI's API data usage policy.
No syllabus images or extracted text are stored by Vusk beyond the current session.

Camera access is requested only when you explicitly initiate a scan. The App does not access your photo library.

4. iCloud & on-device sync

Vusk uses two Apple-managed iCloud mechanisms:

iCloud Key-Value Store (NSUbiquitousKeyValueStore) — stores a single timestamp: when your 14-day free trial began (vusk.trialStart). This allows your trial period to carry over across reinstalls and devices. No personal data is stored here.
App Group UserDefaults — shared local preferences for widgets and extensions. This data never leaves your device.

Your study data (subjects, sessions, assignments) is stored only on-device via SwiftData and is not synced to any server operated by Vusk.

5. Calendar access

If you grant calendar permission, Vusk reads your iOS Calendar locally to find existing exam events and import them into your study schedule. Calendar data is processed on-device only and is never transmitted to our servers or any third party.

Calendar export (Pro feature) writes events to a dedicated Vusk calendar on your device. No calendar content is uploaded anywhere.

6. Screen Time & app blocking

The Focus feature includes optional app blocking powered by Apple's Family Controls / Screen Time framework. This feature:

Operates entirely on-device through Apple's authorized APIs
Does not report which apps are blocked or any usage data to Vusk or any third party
Requires explicit opt-in by you in the App settings

7. Subscriptions and payments

In-app purchases are handled entirely by Apple's App Store and StoreKit. Vusk does not receive, process, or store any payment card information. All billing inquiries should be directed to Apple.

8. Analytics, advertising, and tracking

Vusk contains no analytics SDKs, advertising networks, or third-party tracking libraries. We do not collect device identifiers, usage statistics, or behavioral data. We do not display ads.

9. Data retention and deletion

All study data is stored on your device. You can delete it at any time by deleting the App. Because we do not operate a user account system and do not store personal data on our servers, there is nothing additional for us to delete on your behalf.

The trial start timestamp stored in iCloud Key-Value Store will be removed automatically when you delete the App and your associated iCloud data, or you can reset it via the Developer Menu in Settings.

10. Children

Vusk is designed for students of all ages. We do not knowingly collect personal information from anyone, including children under 13. Because no account creation or personal data submission is required to use the App, the App is suitable for use by minors.

11. Changes to this policy

If we make material changes to this policy, we will update the effective date above and, where appropriate, notify you within the App. Continued use of Vusk after changes take effect constitutes your acceptance of the updated policy.
