Delete your account and data in Kira Lang

In the app

Without the app: request deletion by email

If you have already deleted the app and no longer have the Support ID, we can’t find the record: nothing in it names you. It is erased automatically 12 months after the app last contacted the server (while a subscription is active, it is not deleted). A subscription is cancelled in the store, not by us: how to cancel.

An account issued by us

The app has no sign-up. The only accounts are service accounts that we give to specific people — for example, to an app store reviewer (“Sign in” on the first screen, email and password). If you were given such an account:

• “Delete my data” in the profile erases the data tied to the account on the server (the same list as above) and everything on the phone, and signs you out of the account;
• the sign-in itself — the email address and the password hash in Firebase Authentication — is not erased by the button. To delete the account, write to hello@kiralang.app: we will delete it and reply within 30 days.

How to delete the data on your device

What gets deleted

• Completed lessons, learned words and review progress.
• Experience (XP), day streak, crystals.
• The level and interests you chose, and all settings.
• Reports about AI replies saved on the device.
• When deleting from the app — the data about you on the server as well: the PRO entitlement, the subscription state, records of charges, the daily-limit counters, the notification address, the last-contact marker, the feedback and AI-reply reports you sent (together with the excerpt of Kira’s reply attached to a report).

The app’s anonymous identifier goes along with the data: at the next launch the app will receive a new “Support ID”. Your subscription is neither lost nor cancelled in the process — it is tied to your store account (Google or Apple), and the “Restore purchases” button will bring PRO back to the new installation. Until the subscription is cancelled in the store, the charges continue.

What remains after deletion

The button erases data with us and on the phone. Some information is held elsewhere or stays for a while in copies, and the button does not reach it:

• Server backups. Once a day the server makes a backup and keeps the last 14. Data deleted with the button can stay in those copies for up to 14 days, until newer ones replace them.
• The phone’s cloud backup. If the phone’s operating-system backup is turned on, the cloud copy keeps what was in the app at the time of the last backup: name, questionnaire answers, progress, settings. The button does not erase that copy; you can delete it in the phone’s backup settings. Restoring from such a copy brings the data back to the device.
• Google. The button deletes the anonymous identifier in Firebase; if Firebase refused to delete it (for example, there is no connection), the app simply signs out of it, and the record stays with Google. Analytics events and crash reports that the app managed to send are held by Google under Google’s own rules.
• The store (Google Play or the App Store). Payment details and purchase history stay with the store under its own rules.
• OpenAI. The language-model provider may keep requests in abuse-monitoring logs for up to 30 days under its own rules.
• Service records not tied to your identifier in the app: daily statistics counters (including an estimate of the number of users per day; kept for up to 90 days) and timestamps of moving a subscription receipt between accounts.

The email address from the form on the site

If you left your address in the closed test request form, it is stored on our server. It is the only contact detail of yours that we have.

How to delete it: tap the removal link in any email from us. In Gmail and other mail clients there is a built-in unsubscribe button for this, and it works the same way. The address is erased immediately; all that stays with us is an irreversible hash from which neither the address nor the list of recipients can be reconstructed, and which exists for one purpose only: so that we don’t accidentally write to you again.

If you no longer have the email, write to hello@kiralang.app from the same address and we will delete it manually.

If you never followed the confirmation link in the first email, the address isn’t being used anywhere anyway: without confirmation we don’t write again.

Data on the server

The messages from your conversation with Kira are not kept on the server once she has produced her reply — there is nothing there to delete. The server keeps no request log containing content at all; service logs are limited in size and are automatically pushed out by newer entries.

What is tied to you is kept on the server in this form: the PRO entitlement, the state of the subscription and records of charges, the daily-limit counters, the notification address, the last-contact marker — all linked to the anonymous identifier — and also the feedback and AI-reply reports, if you sent any. The “Delete my data” button in the app erases all of this right away. Without the button this data is deleted automatically 12 months after the app last contacted the server; while a subscription is active, it is not deleted. The store (Google Play or the App Store) keeps its payment records under its own rules.

To stop the renewal, cancel the subscription in the store — in Google Play (Play Store → your profile → “Payments & subscriptions” → “Subscriptions” → Kira Lang) or in the App Store (Settings → your name → Subscriptions → Kira Lang) — that is a separate operation, and we can’t do it for you. Step by step: how to cancel your subscription.

If you need help

Write to hello@kiralang.app and we will help you delete everything connected with you. Your data is not tied to a name or an email, so please attach the “Support ID” from the app: Profile → “How it all works” → at the bottom of the screen, next to the support address, there is a copy button.
