How do I cancel my subscription?

on the web, open the app's Settings → Premium → "Manage subscription". You keep Premium until the
end of the period you have already paid for.
How do I delete my account and data?
To delete your Practical account, provided by Nubico Software Technologies SL:
If you cannot access the app, email hola@nubico.tech from the address you registered with and we will delete it for you within 30 days.
Deleted immediately and permanently: your email, name and password; your learning progress, levels, streaks and results; your mini-game history; your app settings; the messages from your conversations and exercises; and any content reports you sent us. Voice recordings are never stored: audio is transcribed and discarded straight away.
Kept after deletion: billing and tax records of any purchase, which we and our payment providers (Apple, Google, Stripe) are legally required to retain for up to 6 years. These records contain the transaction, not your learning data. Aggregated, non-identifying usage totals may also be kept for capacity planning.
Can I delete my data without deleting my account?
Yes. To erase your learning data from Practical, by Nubico Software Technologies SL,
while keeping your account:
This permanently erases your progress, levels, streaks, situation results, mini-game history and the messages from your past conversations, on your device and on our servers. Your account, email and settings stay as they are, so you can carry on from zero.
To have any other personal data erased or corrected without closing your account, email hola@nubico.tech from your registered address, telling us what you want removed. We answer within 30 days. Billing and tax records of past purchases cannot be erased on request: we are legally required to keep them for up to 6 years.
I lost my progress
Progress is tied to your account. Make sure you signed in with the same email (or the same Google /
Apple account) you used to register.
The microphone or voice isn't working
Check that you granted microphone permission to the app in your system settings, and that you have
an internet connection.
