The short version. Mystra works without you creating an account. What you type into a reading, and any photo of a card spread you choose to upload, is sent to our server and passed to a third-party AI provider so a reading can be written for you. We do not store the content of your readings on our servers — your journal stays on your phone. We show no ads, use no advertising identifiers, and sell nothing to anyone.
Mystra is published by Antaai ("we", "us"). If you have any question about this policy or about your data, write to info@antaaistudio.com.
The first time you open Mystra, an anonymous account is created for you through Google Firebase Authentication. It is a random identifier tied to that installation. It carries no name, no email address and no phone number. We use it to keep track of how many free readings you have used today and whether you have an active subscription.
Mystra may offer to connect a Google account so that a subscription survives changing or resetting your phone. This is optional and nothing in the app requires it. If you accept, we receive the email address and display name of the Google account you pick, and store them in our Firebase project. If you never sign in, we never have them.
When you ask a question, describe a situation, or upload a photograph of a card spread you have laid, that text and that image are sent over an encrypted connection to our server and forwarded to our AI provider, which generates the reading. This is the core function of the app: without sending it, there is nothing to read.
We do not keep a copy of your messages or your photographs on our servers after the reading has been generated.
Purchases are made through Google Play. We use RevenueCat to tell us whether your subscription is active. We receive the status of the purchase and the identifier of the product bought. We never receive, see or store your card number or any other payment details — those stay with Google.
Your journal — the readings you have had and the notes attached to them — is written to storage that belongs to the Mystra app on your own device. It is not uploaded to us. Deleting the app deletes it.
We do not sell personal data, and we do not share it with anyone for advertising.
| Provider | What it handles |
|---|---|
| Google Firebase Authentication | The anonymous account, and your email and name if you sign in with Google. |
| Cloudflare | Runs our server. Your requests pass through it; it stores your account identifier, your daily usage count and your subscription status. |
MiniMax (api.minimax.io) | The AI provider that writes the readings. It receives the text and any spread photograph you send, in order to generate a response. |
| RevenueCat | Tells us whether your subscription is active. |
| Google Play | Processes the payment itself. |
These providers operate internationally, so your data may be processed on servers outside the country you live in, including outside the European Economic Area and outside Türkiye. Each of them is bound by its own agreement with us to process the data only for the purpose described above.
You can delete your account and everything we hold against it from inside the app, under Profile → Delete my account. Full instructions, including how to ask us to do it for you, are on our account deletion page.
Depending on where you live you may also have the right to ask us for a copy of your data, to have it corrected, or to object to our processing it. Write to info@antaaistudio.com and we will answer within 30 days.
Deleting your account does not cancel your subscription. Subscriptions are managed by Google Play and must be cancelled there.
Everything the app sends travels over HTTPS. Our server refuses any request that does not carry a valid authentication token. No system is perfectly secure, but we do not store the content of your readings, which means there is no archive of them to be exposed.
Mystra is intended for adults and is not directed at children. We do not knowingly collect data from anyone under 18. If you believe a child has used the app and given us data, write to us and we will delete it.
If we change how the app handles data we will update this page and change the date at the top. Material changes will also be announced in the app.
