Altura has no account, no servers, and collects nothing about you. Everything you make is stored on your own device.
Last updated 29 July 2026
Altura does not collect, transmit, sell, or share personal information. There is no sign-up, no login, and no profile. We never see your cards, your study history, or how you use the app.
This is not only a policy commitment. The Altura app does not request internet access — you can check this yourself, since Android lists an app’s permissions on its Play Store listing and in Settings, and “Internet” does not appear for Altura. Altura’s own code cannot open a connection to us or to anyone else.
Two Android features can still carry what you have written off your device. Neither is run by us, neither sends anything to us, and both are under your control: Read aloud and Android backup. They are described in “Things that involve someone other than us” below, and we would rather point at them than let a flat “nothing ever leaves your phone” do the work.
Altura uses no analytics, no crash-reporting service, and no third-party tracking. Advertising and paid features are covered in their own section below.
All of this lives in Altura’s private storage on your phone. Other apps cannot read it, and it never leaves the device unless you choose to move it.
Uninstalling Altura, or clearing its storage in Android Settings, deletes all of it. There is no copy anywhere else for us to delete on your behalf.
Altura asks for as little as it can. Each permission is used for one purpose and nothing else.
| Permission | Why | When |
|---|---|---|
| Microphone | To record your own audio onto a card, if you choose to. Recordings are saved in Altura’s private storage; we never receive them. If Android backup is on, they ride along with your other data (see below). | Only asked when you tap record. Decline and the rest of the app works normally. |
| Notifications | To show the optional daily study reminder. | Only if you turn the reminder on. |
| Run at startup | So a reminder you already set still arrives after you restart your phone. | No data is read or sent. |
| Vibration | Brief haptic feedback while studying. | Can be turned off in Settings. |
Three more permissions come from a standard Android library Altura uses to run the daily reminder reliably (Jetpack WorkManager). They may show up in the system’s permission list even though nothing in Altura uses them for anything else: Wake lock, Foreground service, and View network connections.
None of them grants internet access. “View network connections” only lets an app check whether a connection exists; actually sending or receiving data requires the separate Internet permission, which Altura does not have — which is why the claim above holds.
Altura does not request camera, location, contacts, phone, or storage permissions.
Choosing files — importing a deck, exporting, or backing up — uses Android’s own file picker. Altura only ever receives the single file you pick, and only for as long as it takes to read or write it.
There are three places where another party is involved. In each case no data goes to Altura, and nothing happens without you starting it.
Read aloud. When you use Read aloud, Altura hands the card’s text to the speech engine your phone uses — usually Google’s, sometimes another one you have installed. Some engines produce speech on the device; others send the text to their own servers to do it, particularly for a language whose voice you have not downloaded. That choice belongs to the speech engine, not to Altura, and it happens under that app’s permissions rather than ours. If you would rather no card text ever left the phone, leave Read aloud off — everything else in Altura works without it.
When you export a deck or back up your data, Altura writes a file to the location you choose. That file contains your cards and study history in readable form, and a full backup also contains any audio and pictures on your cards. Once it exists it is an ordinary file — if you then share it, its contents travel with it, including those recordings. Treat it the way you would any other document.
Altura is free to use. It is supported by advertising, with paid options that remove the ads. This section describes how both work, so it holds whether or not you are seeing either one yet.
If Altura shows you ads. An advertising partner — a third party, named here once chosen — receives information from your device in order to select them. Typically that is your device’s advertising ID, your IP address, and basic interactions with the ads themselves (that one was shown, that you tapped it). One limit holds regardless:
Your cards, decks, and study history are never part of it. What you are studying is not advertising data, and it is not shared with an advertising partner or anyone else.
You can reset or delete your advertising ID at any time in Android’s settings, and if you are in the EEA or the UK you are asked for consent before any personalised advertising is shown.
If you buy something in Altura. The purchase is handled by Google Play, which acts as the merchant. We never see your card number or billing details — Google processes the payment and tells the app only whether you are entitled to what you bought.
Altura is a general-purpose study tool. It is not directed at children under 13, and it does not knowingly collect information from anyone — including children — because it does not collect information at all.
If this policy changes, the date at the top changes with it. Any change that affects what leaves your device — a new advertising partner, an analytics tool, anything that syncs — is written here before it reaches you, not after.
