Kira Lang Privacy Policy
Effective date: August 1, 2026
Last updated: August 1, 2026
In short
Kira Lang is built so that there is almost nothing to tell about you. There are no accounts and no sign-up. Your progress, words and settings are stored on your phone. We do not sell data, we do not show ads, and we do not share anything with ad networks.
The only thing that leaves your device is the text of what you say to Kira, and only so that she can reply. The details are below.
1. Who processes the data
- Controller: Sofiia Riasna, individual entrepreneur (FOP, Ukraine)
- Place of registration: Odesa, Ukraine
- Email: support@dit-a.com
- Website: dit-a.com
- Full registration details are provided on request at support@dit-a.com

2. What data and why
2.1. Learning progress — stored on your device
Completed lessons, learned words, experience points (XP), day streak, crystals, the level and interests you chose, and your answers to the questions asked on first launch.
This data is not sent to us. It is stored in the app’s memory on your phone and is used to show your progress and to pick scenes for you.
2.2. Google backup
If Google backup is enabled in your phone settings, the app’s data (progress and settings) is included in your backup on Google Drive. This is done by the Android operating system, not by us: we have no access to your backup. You can turn it off in your phone settings.
2.3. Microphone and speech recognition
The microphone turns on only while you hold down the talk button. Nothing is ever recorded in the background.
Speech is recognised by your device’s system services. Depending on your phone model and Android settings, recognition may run directly on the device or through Google’s speech recognition service — this is determined by your system settings. We neither receive nor store audio recordings: only the recognised text is returned to the app.
2.4. Text-to-speech
Lines are voiced by your device’s built-in speech synthesiser. Nothing is transmitted anywhere.
2.5. Conversations with Kira
This section applies when the AI conversation feature is enabled.
So that Kira can reply, the text of your line and several previous lines of the conversation are sent to our server and then to the language model provider. Anonymised learning context is also sent: your level, the lesson topic and the lesson words.
Not sent: your name, your contacts, the contents of your phone, audio recordings.
Please do not write or say personal data, passwords, card numbers or other sensitive information in the conversation — this is a learning conversation and it is processed automatically.
We do not use what you say to train models.
2.6. Reports about AI responses
If you report a response from Kira, the app stores the reason for the report and the text of the reported response on your device. We need this in order to tune filtering. A report contains no personal data.
2.7. Purchases
The subscription is purchased and paid for through Google Play. We do not see, receive or store your card details — they are processed by Google. We only receive confirmation that the subscription is active.
2.8. Diagnostics and analytics
Applies if this feature is enabled in your version of the app.
Anonymised usage statistics (which screens were opened, how long a session lasted) and crash reports help us fix errors. This data does not allow you to be personally identified.
3. What we do not do
- We do not sell data or share it with ad networks or data brokers.
- We do not show ads.
- We do not build profiles for targeting.
- We do not require registration and do not collect contact details.
- We do not read your files, contacts, calls or messages.
4. Who the data is shared with
| Recipient | What | Why |
|---|---|---|
| Language model provider | Text of conversation lines | To generate Kira’s reply |
| Google Play | Payment data | Purchase and renewal of the subscription |
| Server hosting provider | Technical request logs | Operation of the service |
All recipients process the data on our behalf and for the purposes described here.
5. How long we keep it
- On your device — until you delete the app or clear its data.
- Conversation lines on the server — not stored after the reply has been generated.
- Technical logs — no more than 30 days.
- Subscription records — for as long as the subscription is active, and thereafter for the periods required by accounting and tax law.
6. Your rights
You have the right to request access to your data, its rectification or erasure, to restrict processing, to object to it, and to receive a copy of your data.
Since we have no accounts and almost everything is stored on your device, the fastest way to delete your data is to clear the app’s data or delete the app: Phone settings → Apps → Kira Lang → Storage → Clear data.
If you are in the European Economic Area, processing is carried out on the basis of your consent and of the necessity to perform a contract (GDPR, Art. 6). You have the right to lodge a complaint with the supervisory authority in your country.
For users in Ukraine, processing is carried out in accordance with the Law of Ukraine “On Personal Data Protection”.
Requests — to support@dit-a.com. We reply within the periods established by applicable law.
7. Deleting data
In short: delete the app or clear its data in your phone settings. If you purchased a subscription, cancel it in Google Play — this is a separate operation and we cannot do it for you.
8. Children
The app is not intended for children under 13 and does not knowingly collect their data. If you become aware that a child has provided us with data, write to support@dit-a.com — we will delete it.
9. Changes to this policy
We may update this policy. Material changes will be shown in the app before they take effect. The date of the last update is shown at the top.
