Frequently asked questions
Where is my data stored?
Your main data (entries, profile, settings) is on your device — the app does not require a QbaSoft account and does not send entries to a server in the current version of the app. Details: Privacy policy.
How do I create a backup?
In the app: Settings → Backup & restore. You can create a backup manually or enable automatic local backups on your device. You can also share the JSON file (e.g. to cloud storage) — remember it contains your data.
How do I restore a backup?
On first launch, choose Import data, or in Settings → Backup & restore use import from a JSON file. Before import you will see a preview of the backup and choose a strategy (replace or merge data).
Does the app require an account?
No. In the current version of the app you do not need a QbaSoft account. Premium (if you purchase it) is linked to the Google Play account on your device.
Is Premium free right now?
Yes — until 28 February 2027 (launch promotion). Every user gets full Premium automatically, with no card and no subscription. After updating, existing users may see a one-time “Premium on start” message. You can also see the promotion status in Settings → Premium Account.
During the promotion the app does not offer a new Monthly/Yearly purchase — Premium is already available. After 28 February 2027, users without a Google Play subscription return to Free and subscription offers return; your data stays unchanged. Existing store subscriptions are not cancelled.
How do I manage Premium / subscription?
During the launch promotion a subscription is not required (and a new purchase is not offered in the app). After it ends, payments and subscriptions are handled by Google Play:
- purchase and renewals — through your Google account,
- cancellation — Google Play → Payments & subscriptions → Subscriptions,
- restoring Premium after reinstall — Restore purchases in the app (same Google account).
QbaSoft does not process card payment data. If Premium does not unlock after payment — write to qs-alco-rhythm@qba-soft.pl with the app version and a description of the situation.
What if backup import fails?
Check that the file comes from QS AlcoRhythm (JSON, backup schema). On validation error the app will show a message — do not email your full entry history unless we ask for it in a specific case. Describe the error, app version, and where the file came from (manual export, automatic backup, old phone).
Where do the calories on an entry come from?
These are approximate calories from ethanol only: grams of pure alcohol × 7. Sugars, carbohydrates, and mixers are not included — this is not the calorie content of the whole drink. Shown on the entry, as a daily total on Today, and next to the date in History. Available in Free and Premium.
I see an update message. Do I have to update?
Not for now. You can choose Update or Later (a reminder after about a day). The app does not block use when an update is not required. In the future QbaSoft may require a minimum version — then you will see a required-update message.
Premium and subscription — quick reference
QS AlcoRhythm offers an optional Premium plan with additional features described in the app. Until 28 February 2027, full Premium is available under the launch promotion (no card, no subscription).
What we can help with:
- Premium not unlocking after purchase,
- questions about Premium feature scope,
- the app not seeing an active subscription despite payment.
What we cannot handle directly:
- refunds — handled by Google Play,
- changing payment method — through your Google account settings.
