StudyNext Terms of Service

Last updated: September 30, 2026

1. Service and eligibility

StudyNext is a study support app offering deadline-based planning, memorization and review, a timer and Study Rooms. Schedules and review intervals are guides, not guarantees of exam results or other outcomes. Children under 13 may not use the App. Minors should obtain guardian consent where required by law.

Suggested tasks and review times are calculations based on your input and use. Decide how to study and prepare for exams in light of your own circumstances. Available features and displayed results may vary with the App and connected services.

2. Data and account

You can use study data on your device. When you connect an Atmosphere account through AT Protocol, records such as plans, activity and Study Room messages and status are public on the account's data storage service (PDS). StudyNext's display and search service (AppView) also stores current record contents. Hiding a record in the App does not make its source private; others may copy it. Do not post sensitive information. See the Privacy Policy for data handling.

Authentication normally uses OAuth; an app password is optional. Sessions and credentials are stored on your device or browser. Please protect your account and device. StudyNext does not store app passwords on its service.

The App's “Delete all data” feature requests deletion of StudyNext records from your PDS and clears local data; it does not delete your account. When StudyNext learns that a record was deleted, it removes the corresponding contents from AppView. StudyNext cannot delete copies held by others or data on your PDS itself. Back up or export important data.

Connected records include Study Room posts and study activity. Because they are public, do not post other people’s personal information or content you have no right to publish. Deleting your records may not remove information received by others or copies they already saved. If deletion stops partway through, local data is not cleared and an error is shown, but some PDS records may already have been deleted; check the result and retry.

3. Support purchases

Optional support purchases do not unlock features or provide content. iOS and Android purchases are paid through Apple App Store or Google Play, with RevenueCat used to manage purchases. Web support opens Stripe checkout. Refunds and cancellations follow applicable law and the relevant payment provider's policies. See the legal notice.

Native support purchases are consumable, not recurring subscriptions. Web support is paid per transaction. Purchase steps, receipts and refund request channels differ by payment method. This does not limit rights to a refund under applicable law.

4. Prohibited conduct and moderation

Do not harass, discriminate against or defame others; send spam or unauthorized ads; access systems without authorization; overload services; collect or disclose others' personal information without permission; or deliberately falsify study records. This does not restrict acts permitted by law. The operator may restrict visibility of posts or access, or take other proportionate action in response to violations. Reports are used for review and response.

The following are also prohibited in shared spaces:

• Threats, persistent harassment and posts contrary to public order
• Impersonation or collecting, reposting or spreading others’ study records or personal information without permission
• Malicious software, spam, attacks on systems or interference with their operation

The operator will consider the nature and impact of a violation. Hiding a post within the App does not necessarily remove its public source record or copies held by others. Report violations or safety concerns through the App or contact us.

5. Service risks and responsibility

Network failures, device or external storage-service outages, and changes to services may interrupt sync, display or availability. Users should generally resolve disputes between themselves but may report problems to us. Independent storage and payment providers have their own terms.

Back up or export important study data periodically in case records are lost or sync fails. Device failures, network problems, connected service outages and copying by third parties are not all within StudyNext’s control. This does not categorically deny liability for failures of StudyNext-operated services or the operator’s conduct. Applicable law determines how specific losses and claims are handled.

6. Changes, suspension and closure

Features may change, and service may pause for maintenance, incidents or unavoidable circumstances. If the service closes, we will try to give advance notice where practicable and offer an opportunity to export study data. Where events beyond our reasonable control, such as natural disasters, interrupt or delay the service, liability remains subject to applicable law.

Part of a feature or service may be suspended without advance notice when urgent safety action makes notice impracticable. Technical or legal constraints may prevent notice or an export opportunity before closure. Please check your data on your device and connected services regularly.

7. Rights

Rights in App materials and code belong to the operator or their respective owners; open-source components remain subject to their licenses. These Terms do not restrict uses allowed by law or by those licenses. Rights in user-submitted content remain with the user or original rights holder. Users grant the operator a royalty-free, non-exclusive license only as needed to sync, store and display their content to provide the service.

Third-party materials remain subject to their own rights and conditions; these Terms do not transfer those rights to the operator. The operator’s permitted use of user posts is limited to what is needed to provide the App and StudyNext’s display and search service, including sync and display.

8. Changes to Terms and disputes

Changes to these Terms follow applicable law. We will announce the changes and effective date in advance in the App or on the official site; continued use alone is not treated as consent to a change. Japanese law governs these Terms; disputes, claims and venue are subject to applicable law. Contact contact@studynext.app or the contact page.
