Privacy Policy

Who this covers

Breve is an app for iPhone and iPad, built by Irakli Chkuaseli. This policy covers it and this website. It does not cover Apple's services, which are governed by Apple's own privacy policy.

What Breve stores, and where

Breve keeps two separate stores on your device, and the split is deliberate.

Stored on your device and synced through your iCloud

Your decks, cards, review and scheduling history, the patterns derived from that history, and journal notes you write yourself. This travels through your own iCloud account, between your own devices, using Apple's CloudKit. It does not pass through any server belonging to Breve, because there isn't one.

Stored only on the device that created it

The working material behind generation and capture stays on the device that made it and never syncs: generation tasks, runs and proposals, source material you add, transcripts, readings, comprehension records, generated briefs, and the record of answers you typed wrong, which Patterns counts. When you record a class, the audio is never written to disk: it is turned into text on your device, and only the transcript is kept. Speaking passages and their transcripts are local too, and replay audio is temporary.

What you keep from that work joins your library and syncs with it: cards you accept, and a class's topics and grammar coverage. Audio or images you add to a card sync with the card.

What actually leaves your device

Apart from cloud AI, described next, these are the only things that leave your device. Only the first carries anything you have studied, and it goes only to your own iCloud.

Your own iCloud sync

If iCloud is on for Breve, your library syncs through your own Apple account, between your own devices: decks, cards and their images and audio, review history, projects and class schedules, class topics and notes, and the grammar lessons you have unlocked. Apple handles that, in your private iCloud database.

A configuration check

Breve checks Firebase Remote Config for its settings when it opens, and listens for updates while it runs. The app's privacy manifest declares what that carries: your device's country or region, language, time zone and OS version, the app's identifiers, and a per-install Firebase identifier. It happens whether or not you use AI, and it carries nothing you have studied.

A device check

Breve uses Apple's App Attest through Firebase App Check to confirm that requests come from a genuine copy of the app. This attests the device, not you.

Speech models, when needed

Class recording turns speech into text on your device. If the model for a language is missing, Apple downloads it. Nothing you say is uploaded to get it.

Purchases

Apple processes subscriptions through StoreKit. Breve reads the subscription status from StoreKit, and never sees or stores payment details.

Artificial intelligence

Each feature has its own route. Some never use a model, some run only on your device, and some Pro features use a cloud model.

• Built in. Dictionaries, word forms, grammar catalogs and lessons, and the counting behind Patterns are part of the app. None of it uses a model.
• Apple's on-device model. With Pro: tag suggestions, help writing a card, single-word translation and the coach. This work does not leave your device.
• Apple's Private Cloud Compute. With Pro: new cards for a deck, the coach, and the explanation behind "Why this card". Apple states that it cannot read this content and does not keep it.
• Google's Gemini, through Firebase AI Logic. Only with a Breve Pro subscription, and only after you give explicit consent to cloud processing. It reads the pages, photos and class material you choose to send. With your consent, some Pro features may use it in place of an on-device model, and it can stand in when another route cannot do the job. Free users never reach it.

A cloud request carries what its feature needs. New cards for a deck carry the words already in it and how they are going. "Why this card" carries that card and its review history. Before a page is sent, you see it exactly as it will be sent, and you can crop it, cover parts of it, or keep it on your device. Raw microphone audio is never sent to Gemini.

Google says prompts and responses sent this way are not used to improve its products. It may keep them for up to 55 days to detect abuse, and authorized Google staff may review content flagged for abuse. Breve cannot choose the country where they are processed. Until you consent, nothing is sent to Gemini. Consent given against an older version of this document does not carry over to this one.

Permissions Breve may ask for

Breve asks for a permission only at the moment a feature needs it, and declining leaves the rest of the app working. It may ask for notifications and study alarms, and for the camera when you photograph a page. Recording a class uses the microphone and speech recognition, and speech is turned into text on your device. Recording audio for a card uses the microphone only.

What Apple's App Store label says

Breve's privacy manifest declares three categories, all marked "Data Not Linked to You", none used for tracking:

• User content. The cards and notes you write, used only to run the app.
• Photos or videos. A page you photograph or choose, used to propose cards from what is on it.
• Diagnostics. The launch-time configuration fetch described above.

Breve contains no advertising, no analytics SDK, and no tracking domains.

Children

Breve is not directed at children, and does not knowingly collect personal information from them. Breve has no account and no server of its own, so it holds no personal information about anyone anywhere but on their own devices and in their own iCloud. Your cards, notes, photos and transcripts may contain personal information, and they stay with you.

Keeping and deleting your data

Breve holds nothing about you on a server, so there is nothing to request from it and nothing for it to delete. Deleting the app removes everything stored on that device. Anything synced sits in your own iCloud account and is managed from iOS Settings, where you can delete Breve's iCloud data yourself. Purchase records belong to Apple.

Changes to this policy

The version at the top identifies this exact revision. Breve binds consent to this page's address and its version: consent recorded against one version does not transfer to another, so a new version asks you again rather than assuming.

Contact

Questions about privacy in Breve go to privacy@breve.cards.

If you report a problem with a grammar lesson, Breve prepares an email to feedback@breve.cards, in Mail inside Breve or in your own mail app. It includes the lesson, the reason and note you give, the languages you study and read in, and the app's version. You read it and send it yourself. Nothing is sent unless you do.
