Privacy Policy

Information stored on your device

Arivu stores decks, cards, review history, scheduling data, settings, imported media, backups, and card reports on your device. This information is used to provide review, import, backup, search, audio, and course features.

Arivu can use Apple system voices to read card content. Speech synthesis is provided by iOS. Imported files are processed by the app.

Optional iCloud Sync

iCloud Sync is optional and off by default. If you enable it, Arivu stores a copy of your learning library in your private Apple iCloud database so that your saved work can appear on your Apple devices. The synced copy may include decks and cards you create or import, notes and bookmarks, study and review history, scheduling state, preferences, deletion and restoration records, and images or audio you add to cards.

Arivu saves every review and edit on your device before sync begins, remains usable offline, and does not require iCloud to open or study your library. Built-in curriculum and bundled recordings are reconstructed by the app; sync stores their stable identity and your learner state rather than uploading a second copy of the bundled content.

Arivu uses Apple's CloudKit service and the private database associated with your Apple Account. Sensitive inline record content uses CloudKit encrypted fields. CloudKit encrypts asset files such as larger payloads and user-added media automatically. The developer does not operate a separate server for your synced library and does not use the synced data for advertising, tracking, analytics, or marketing. Apple's handling of iCloud data is also governed by Apple's privacy policy and your iCloud settings.

Turning iCloud Sync off stops Arivu's sync connection on that device and keeps the local library available. It does not delete the copy already stored in iCloud or change the setting on another device. “Reset Sync Connection” keeps both the local library and iCloud records; it clears reconstructible connection state and downloads changes again. You can manage or delete Arivu's stored iCloud data through your Apple Account's iCloud storage controls. Disable sync on your other devices first if you do not want them to upload their local copy again.

Information you choose to send

Card reports

When you submit a card report, Arivu saves it on your device and sends the card prompt and answer, deck name, selected problem, optional notes, app and iOS versions, and relevant audio diagnostics. Audio diagnostics can include whether prompt or answer audio played, the text sent to speech, language code, voice identifier, voice name, voice language, and voice quality. Reports do not include an Arivu account, contact address, advertising identifier, or device identifier. If sending fails, the report remains on your device for retry.

Support requests

When you use the support form, the site stores the reply email, topic, message, optional app version, submission time, and a random support reference. The email is used to respond to the request.

Network and hosting information

The Arivu site and report service run on Cloudflare. Cloudflare processes network information needed to deliver the site, protect the service, and enforce request limits. The Arivu database does not store your IP address. The service uses the request address transiently as a rate-limit key and does not write it to the report or support tables.

The public website does not set advertising or analytics cookies. It does not include advertising pixels or social-media trackers.

How information is used

• Card reports are used to investigate and correct sounds, answers, prompts, and formatting.
• Support requests are used to answer questions, investigate app behavior, and process privacy requests.
• Information is not sold or used for advertising.

Sharing

If you enable iCloud Sync, synced library information is processed by Apple through CloudKit in the private database associated with your Apple Account. Information you submit through card reports or support requests is processed by Cloudflare as the service provider that hosts the site, Worker, and database. Information may also be disclosed when required by law or needed to protect the service and its users. It is not shared with data brokers or advertising networks.

Retention and deletion

Card reports that could not be sent remain on your device until you retry or delete them, or remove the app data. Resolved card reports and support requests are deleted from the service after 90 days. Unresolved records are deleted after one year.

To request deletion of submitted information, use the support form and choose Privacy or deletion request. Include the support reference, card prompt and deck, or approximate submission date needed to locate the record. Because Arivu does not create an account or store a device identifier, a report may not be identifiable without those details.

Your choices

• Leave iCloud Sync off if you do not want Arivu to store a copy of your library in iCloud.
• Turn iCloud Sync off on a device to stop its connection while keeping the local library available.
• Manage or delete Arivu's stored iCloud data through your Apple Account's iCloud storage controls.
• Do not submit a card report if you do not want it transmitted.
• Delete or edit a failed card report before retrying it.
• Do not use the support form if you do not want to provide a reply email.
• Request deletion through the support form.

Children

Arivu is not directed to children under 13, and the report and support services are not intended to collect information from children under 13.
