Duality Terms of Use
Last updated: 13 November 2026
These terms apply when you download and use Duality, a grudge journal for iPhone. By using the app, you agree to them. If you don’t agree, please don’t use the app.
Who we are
Duality is developed by Anatolii Zverev, an individual developer based in Israel.

Apple’s terms
You get Duality from the App Store, so Apple’s Standard End User License Agreement also applies. These terms add to it. If they conflict, Apple’s agreement wins in what concerns Apple.
Who can use Duality
You must be at least 13 years old. In the European Economic Area, if you are under 16, a parent or guardian must agree to analytics and crash reports on your behalf (see the Privacy Policy).
Your license
We give you a personal, non-exclusive, non-transferable license to use Duality on Apple devices you own or control, as allowed by the App Store rules. You may not copy, resell, or reverse engineer the app, except where the law allows it.
Your journal
- What you write is yours. It is stored on your iPhone and, if you turn on sync, in your private iCloud. We never receive it.
- You are responsible for what you write and for keeping copies. We can’t see your journal, so we can’t restore it if it is lost. Use Export to keep a backup.
- iCloud sync depends on Apple’s service and your iCloud account.
A journal, not a call to action
Duality helps you sort out your feelings. Words like “revenge” and “enemies” in the app are part of its playful tone. The app doesn’t encourage you to harm anyone or break the law, and you agree not to use it to plan or record harassment, threats, or other unlawful acts.
Duality is not therapy or medical advice. If you feel unsafe or in crisis, contact local emergency services or a professional.
Purchases
If the app offers in-app purchases, for example tips, Apple processes the payment. Refunds are handled by Apple under its rules. A tip is a voluntary thank-you and doesn’t unlock extra features unless the purchase screen says so.
Privacy
How we handle data is described in the Privacy Policy.
Changes and availability
We may update, change, or stop offering Duality. When these terms change, we update the date at the top. If you keep using the app after a change, you accept the new terms.
Warranty and liability
Duality is provided “as is”. To the extent the law allows, we don’t guarantee that the app is free of errors or always available, and we are not liable for indirect damages or lost data.
Nothing in these terms limits liability that can’t be limited by law, such as for intent or gross negligence, or the mandatory rights you have as a consumer where you live.
Governing law
These terms are governed by the laws of Israel. If you are a consumer in the European Union or another country with mandatory consumer protection, you keep that protection and can go to the courts where you live.
