RectoVerso is made by Simon Pinkas, Chemin de Floréal 4A, 1024 Ecublens, Switzerland. Questions about this policy: rectoverso@code-think.com, or by post to that address.

• Your study library: cards, review history, imported decks, pictures and sounds are stored on your iPhone. The app does not send them to us or to an analytics service. Widgets and the share extension use storage shared with the app on your device.
• Cards made from text: Apple Intelligence drafts the cards. From version 1.1, cards from an English text are written by Apple’s Private Cloud Compute: the text you chose is sent to Apple’s servers to write them, and Apple does not store it or make it available to anyone, us included. With Settings › Making decks › Private Cloud Compute turned off, or without a connection, your iPhone’s on-device model writes them instead, and the text stays on your iPhone. RectoVerso does not send your text to any other service.
• RectoVerso Pro: from version 1.1, RectoVerso Pro is bought in the app through the App Store. Apple handles the payment: we don’t receive your payment details or your Apple Account. To know whether you have Pro, the app asks the App Store, through Apple’s StoreKit, whether you bought it, or bought RectoVerso before it was free; no server of ours is involved.
• The Deck gallery: from version 1.1, the gallery’s list of decks and the decks you add are downloaded from Apple’s servers, as the app’s own App Store content. iOS downloads the list with the app and its updates, and a deck only when you add it. Apple handles these downloads under its privacy policy; no server of ours is involved, and the app doesn’t send us which decks you look at or add. A deck you add is stored on your iPhone with the rest of your library.
• Maps on cards: from version 1.1, a card that names a place can show it on Apple Maps’ satellite imagery while your iPhone is online. To draw it, the app asks Apple Maps for the map around that place, and Apple handles the request under its Apple Maps privacy policy. The app doesn’t use your location. Settings › Review › Live maps turns the maps off, and the card then shows its own picture.
• Pages and documents you share: the share extension reads the page content, text or supported document you give it, including PDFs. It passes the resulting cards, or text saved for later, to the app through local shared storage. It does not fetch the contents of a bare web link. If you select a file stored with a cloud provider, iOS may download it so the app can read it.
• Reminders: review reminders and notices about material saved from the share extension are local notifications. They do not use a notification server operated by us.
• Links: Support and Privacy policy open this website in your browser. App Store and other external links are handled by the destination service under its own privacy policy.

Automatic backups are on by default. When iCloud Drive is available, RectoVerso saves a library backup in Files › iCloud Drive › RectoVerso when a weekly backup is due and after an import. Backups wait until the app is idle. Turn them off in Settings › Back up to iCloud Drive.

The app normally keeps the four newest backups of the current library and the newest backup of each other library. Backups it cannot read may be kept rather than automatically deleted. A backup includes your decks, media, review history and library settings. Apple transfers and stores these files in your own iCloud account under its privacy policy. We cannot access them. If iCloud Drive is unavailable, the app cannot save an automatic backup there.

Your iPhone’s own backups to iCloud or a computer may also include the app’s data. These are separate from RectoVerso’s automatic library backups.

Manual backups and Anki exports go where you choose in the system’s file or share sheet. A cloud folder or another app you choose may transfer the file under that service’s terms.

Deleting data: removing the app does not remove backups or exported files you have saved elsewhere. To remove those copies, delete them from their storage locations, including iCloud Drive and any device backups you maintain. Turning off automatic backups stops future copies; it does not delete existing ones.

If you contact us, we receive your email address, message and any files or screenshots you choose to send. These are handled through email services and used to answer your request and investigate problems. Please send only what is needed, especially if a deck contains personal or sensitive information. We keep correspondence only as long as needed to handle the request, related follow-up and any legal obligations.

If you test through TestFlight, Apple automatically collects crash logs and beta usage information and shares them with us. This can include device and OS details, installs, sessions and crashes. Apple also shares feedback and screenshots you submit. If you join only through a public link, your name and email address are not shown to us unless you provide them separately.

We use beta information to investigate problems and improve RectoVerso. Apple retains beta feedback for one year and may retain crash and usage data until bugs are resolved. See TestFlight & Privacy for the information Apple collects and shares. This beta reporting is separate from the app, which contains no analytics SDK.

• Hosting: Vercel hosts this site. To deliver pages and protect the service, it processes technical information such as your IP address, approximate location derived from it, requested pages, and browser and system details. We do not use this information to build advertising profiles.
• Storage and transfers: Vercel may process information in the United States and other countries where it operates. Its Privacy Notice describes retention, international transfers and safeguards, including the Swiss–U.S. and EU–U.S. Data Privacy Frameworks and standard contractual clauses where applicable.
• Light or dark: your browser stores your selected appearance locally so it can use it on your next visit. We do not send this preference to a server. Clearing this site’s browser data removes it.
• No advertising or analytics: the site does not set cookies or include analytics, advertising or tracking scripts. Fonts and pictures are served by this site. Following an external link takes you to a service with its own privacy practices.

Under Switzerland’s Federal Act on Data Protection and, where applicable, the EU’s General Data Protection Regulation, you can request access to personal information we hold about you and ask for it to be corrected or deleted, subject to the applicable legal conditions.

Write to rectoverso@code-think.com. We can address information you sent for support or that we received through TestFlight, and help direct requests involving our website host. We cannot access or delete the study library on your device or backups in your own accounts.

You can also complain to Switzerland’s Federal Data Protection and Information Commissioner, or to the relevant data protection authority where you live in the EU.

Changes to this policy are posted here with an updated date. This revision adds, from version 1.1, the Deck gallery’s downloads from Apple’s servers and the maps Apple Maps draws on cards. The one before it added Apple’s Private Cloud Compute, which writes cards from an English text, and RectoVerso Pro’s purchase through the App Store.
