Dune Privacy Policy

1. Scope

The App provides virtual altar and meditation spaces, daily practice records, music and singing-bowl sound management, portable space content packages, and optional individual, Dharma teacher, or temple verification.

A Dune account is not required for ordinary use, and the App does not automatically upload on-device practice data to our servers.

2. Information Stored on Your Device

The following information is generally stored only on your device:
• Language, display, notification, music, and sound settings;
• Space names, backgrounds, visual-effect placement, and other configurations;
• Wishes, offerings, bowing, meditation, lotus progress, and related history;
• Images, audio, and space content packages you select, create, or import;
• Cached subscription display state.

Deleting the App, clearing its data, or changing devices may result in data loss. Restoring purchases restores eligible App Store or Google Play subscription access, not on-device content.

3. App Store and Google Play Subscriptions

Apple or Google Play, depending on your device, processes subscription purchases, billing, renewal, cancellation, refunds, and transaction validation. The App receives product identifiers, purchase status, and other data needed to determine subscription access through the applicable store.

We do not receive or store your full payment-card details or store-account password. Apple or Google handles purchase data under its own privacy policy.

4. Optional Account Verification

Account verification is optional. Users who do not apply are not required to provide us with a name, email address, phone number, profile image, or supporting documents.

When applying for individual, Dharma teacher, or temple verification, the App creates a .lamaverify package on the device. It may contain a public display name, contact details, biography, profile image, and identity, teacher, or temple documents selected by the applicant. The package leaves the device only when the user actively sends it by email or another chosen method.

We use received materials only to verify identity or authority, prevent impersonation, contact the applicant, issue signed credentials, and handle related disputes. A verification badge confirms review of the named creator; it is not an endorsement or guarantee of the creator's content, religious views, or results.

5. Photos, Files, Email, and Notifications

The App opens the system photo or document picker only after a user action and processes only the items the user selects. Verification applications and package sharing may open the system mail composer or share sheet. The App does not send the item until the user confirms the system action.

Notifications are used for meditation timers or reminders enabled by the user. Permissions can be changed at any time in system settings.

6. Content Packages and User-Initiated Sharing

Users may create, import, and share practice-method or meditation-sharing packages. Sharing occurs only after the user invokes the system share function. Before importing a third-party package, users should verify its sender, source, and contents.

Packages should not contain personal practice history or plain-text verification email addresses and phone numbers. A package from a verified creator may include the public name, verification type, credential identifier, and cryptographic signatures or hashes used for verification.

7. Data We Do Not Collect and Tracking

The App does not contain third-party advertising, behavioral advertising, or cross-app tracking SDKs, and we do not sell personal information. During ordinary use, we do not actively collect precise location, contacts, IMEI, MAC address, continuous camera or microphone content, calls, or screen-sharing content.

The App offers optional Study Space and class sync as described in section 13. Practice records are not used for advertising, profiling, or data brokerage.

8. Sharing of Information

We share necessary information only with:
• Mail, file, or sharing services selected by the user;
• Apple or Google Play for subscription and payment processing;
• Authorized personnel who review verification materials;
• Authorities when required by law, court order, or a valid governmental request; or
• Other parties at the user's explicit direction or with the user's consent.

Anyone processing information on our behalf must provide protections consistent with this Policy.

9. Retention, Deletion, and Your Rights

Users control on-device data through the App's features or by deleting the App. Verification materials are retained only as long as reasonably necessary for review, credential administration, fraud prevention, dispute handling, and legal compliance, after which they are deleted or de-identified as appropriate.

Subject to applicable law, users may request access to, correction of, restriction of, or deletion of verification materials we hold, and may withdraw an incomplete application. Contact support@yoshinn.com or dune@yoshinn.com. We may verify identity before fulfilling a request to prevent misuse.

10. Security

We use safeguards appropriate to the information, including access controls for review materials, file-integrity hashes, digital signatures for credentials, and restricted review devices and signing keys.

No electronic storage or transmission method is completely secure. Users should also protect their device, email account, exported packages, and credential files.

11. Children

Users below the legal age in their location should use the App with the consent and guidance of a parent or legal guardian. When a minor applies for account verification, we may request guardian consent where required by applicable law.

12. Teaching Recordings, Reports, and Safety Lists

Verified users may choose to record teaching audio. Microphone access is requested only when recording begins. Recordings, drafts, playback progress, and imported teaching audio are stored on the device; Apple TV receives teaching audio only through user-initiated local-network sync. Dune does not automatically upload complete recordings.

When a user submits a report, the App may send the package ID and version, teaching ID, creator credential ID, audio SHA-256 fingerprint, selected reason, optional explanation, and submission time. Reports made while offline remain queued on the device until delivery succeeds. The App periodically downloads a Dune-signed safety list of disabled credential IDs or audio fingerprints and keeps the last successfully verified list for offline protection. Normal network request information, such as IP address and time, may be processed by our server for delivery, security, abuse prevention, and troubleshooting.

13. Optional Study Space and Class Sync

Personal mode can download scripture audio from the platform library and keeps personal practice records on your device. Browsing or downloading audio sends the request information needed to provide the service to the platform and file storage provider.

When you use a class number or QR code to apply to a class, the platform processes your email address, name or Dharma name, invitation code, App installation identifier, and class membership. The class administrator reviews the application; no Dune account registration is required. Once approved, scripture and audio version identifiers, completed counts, completion times, and teaching listening progress recorded for that class are automatically synced for teaching administration and statistics. Joining does not automatically upload personal practice history or share records from another class.

Application and class-access credentials are stored in secure device storage. Withdrawing an application or leaving a class removes the relevant credentials and ends further access to that class content, but does not automatically delete records already synced. Contact the class administrator or support@yoshinn.com about cloud-held information.

14. Daily Wisdom, Events, and Submissions

Daily wisdom and Buddhist events are downloaded from Dune Academy (https://dune.yoshinn.com). Favorites and saved content remain on your device for offline use. Language and region preferences are selected manually; the App does not obtain your GPS location. Network requests include the information needed to deliver and protect the service.

Verified individuals, Dharma teachers, and temples can submit wisdom or CSV files. Submissions include the text, teacher name, submission type, optional source links, explanation, translations, and notes, together with the submitting credential and installation identifier. Submitted material is stored for duplicate checks, source verification, editing, and publication. Published wisdom identifies the teacher and source; the contributor is not automatically treated as the teacher.

15. Optional Personal Practice Sync and Rankings

Personal practice statistics are calculated on your device. Personal cloud sync is off by default. Browsing the public ranking does not enable practice uploads. The App creates a random installation identifier and device public key for secure access.

If you enable personal sync, the platform receives eligible personal record identifiers, practice type or scripture/audio identifiers, counts or minutes, completion dates and time-zone information. These records may reveal religious practice. Public rankings are limited to participating devices without active class membership and display an anonymous alias and totals for the selected project, unit, and dates, not your email or full record history. Class records are kept separate and follow section 13.

Disabling sync stops future personal uploads; it does not automatically erase records already stored in the cloud. Permanently deleting a supported local practice record queues deletion of its synced counterpart for the next enabled sync. To request deletion of all cloud-held personal records or installation information, contact support@yoshinn.com; we may verify control of the device or relevant credential.

16. Cloud Retention and Access

Class information, submissions, security credentials, and opt-in personal records are retained only for providing the requested functionality, administering credentials, addressing disputes, and meeting legal obligations. Access is restricted to authorized administrators and service operators. Cloud transfers use HTTPS. Data is not used for advertising or cross-app tracking and is not sold. You may contact support@yoshinn.com to request access, correction, or deletion of cloud-held information. Uninstalling the App alone does not erase cloud-held data.

17. Changes and Contact

We may update this Policy as the App, applicable law, or app-store requirements change. Material changes will be communicated in the App or on our official website as appropriate.
