Frequently asked questions
Is a credit card required to start the trial?
No. The trial starts when you install the APK from this site, with no sign-up and no card. A card is only needed when you subscribe, after the trial.
How many devices can I use?
One active device at a time. Transfer from Settings → Deactivate licence — released immediately.
How does payment work?
Secured by Lemon Squeezy, credit card or PayPal. First payment at sign-up, then an invoice (excl. VAT) by email at each renewal.
Can I switch from monthly to annual?
Yes. Email us — migration with pro-rata calculation.
Are my data kept if I cancel?
Your data stays on your device. After cancelling, creating new projects is blocked. Existing projects stay editable and their reports can still be exported.
Does the app work offline?
Yes. Measurements, calculations and reports all work offline. A connection is useful on first launch to confirm the trial, and required to activate the licence key.
