Terms of use

Last updated 13 October 2026

The short version. Operarius is free, and an account is optional. Reminders are dependable, but your phone can delay or silence them, so please don't rely on Operarius alone for anything where a missed reminder could cause harm.

1. Who you're agreeing with

These terms are between you and Oleksandr Shabaldas, Slovakia, the developer of Operarius ("I", "me"). By installing or using Operarius you accept them, together with the Google Play Terms of Service.

2. Your licence

I give you a personal, non-exclusive, non-transferable licence to use Operarius on devices you own or control. Please don't copy, resell, modify or reverse-engineer the app, except where the law allows it.

3. Your account

An account is optional. Without one you can use Operarius as a guest, except for backups (export and import), which need an account. I may later ask everyone to sign in. If I do, the app will say so, and your plans stay on your phone.
Sign in with Google or with an email address and password. Keep your password to yourself. You're responsible for what happens with your account.
You can delete your account at any time: Settings → Account → Delete account, or as described on this page.
I may suspend an account that's used to abuse Operarius or other people, or that breaks the law.

4. Reminders

Operarius schedules reminders with Android's exact alarms. Whether and when one reaches you also depends on your phone: battery savers, Do Not Disturb, silent mode, restrictions some manufacturers add, the phone being off or out of power, and the permissions you've granted (Settings → Reminders shows what might get in the way). I can't guarantee that every reminder arrives on time. Don't rely on Operarius as the only reminder for medication, medical care, safety, or legal and financial deadlines.

5. Your data and backups

Your plans are stored on your phone (see the privacy policy). Please keep backups: uninstalling the app, clearing its data or losing the phone can erase them, and I can't recover data I never had.

6. Calendar sync and other services

Google Calendar and Google Maps are third-party services under their own terms. Calendar sync can add, change and delete events in the calendars you choose, following the changes you make in Operarius.

7. Changes to the app

I keep improving Operarius, so features can change.

8. Liability

Operarius is provided with the care of a professional developer. Nothing in these terms limits liability that can't be limited by law, including for intent, gross negligence, and injury to life or health, or your rights as a consumer. Otherwise, to the extent the law allows, my liability is limited to the amount you paid me for Operarius in the 12 months before the claim, and I'm not liable for indirect losses such as missed appointments.

9. Law, complaints and disputes

These terms are governed by Slovak law. If you're a consumer, you also keep the protection of the mandatory laws of the country where you live, and you can bring a claim in its courts. Send complaints to gamedev@ittt-production.uk; I answer within 30 days.

10. Changes to these terms

If I change these terms, I'll update this page and its date. Important changes will be shown in the app before they apply to you.
