Terms of Service
Effective: 3 Oct 2026 · Developer: TRAN HUU DANH (individual developer), operating as 1010 Creative
1. Acceptance
By downloading, installing or using "Duoly - a couple app" (the "App"), you agree to these terms and confirm that you have read the Privacy Policy. If you do not agree, please do not use the App.
2. The service
The App is a private space for couples: counting days together, notes and photos, milestones, daily moods, widgets and an AI writing assistant. The Free tier has rewarded ads that you choose to watch (section 6). It is not a social network, not a tool for monitoring another person, and not a counselling or medical service.
3. Accounts
Some features (such as sync) require an account. You are responsible for keeping your sign-in credentials safe on your device and for providing accurate information.
4. Your content
Notes, photos, dates and everything you create belong to you. You grant us only the technical rights (storage, sync, backup) needed to operate the features you use — nothing more. We never use your private content for advertising, never share it with advertisers and never sell it.
5. Premium and billing
Duoly Premium offers Monthly and Yearly auto-renewing subscriptions and a one-time Lifetime purchase. Prices are shown in-app and billed through Google Play. Subscriptions renew until cancelled in Google Play’s subscription settings; cancellation takes effect at the end of the paid period. Purchases can be restored with "Restore purchases" in the App.
Lifetime note: buying Lifetime while a subscription is running supersedes its benefits, but the old subscription does not cancel itself — you must cancel it in Google Play. The App shows this reminder before and after purchase.
The Free tier always keeps access to the data and memories you created; Premium extends additional features and has no ads.
6. Advertising
The Free tier uses rewarded ads served by Google AdMob: when you want an AI write, you can choose to watch one ad in exchange for one write, or open Premium. Ads appear only when you tap to watch — no banners, no ads that pop up on their own. Premium and the free trial have no ads.
A write is granted only when the ad finishes. If no ad is available, the ad fails, or you close it early, no write is granted. We may cap the number of rewards per day, and may change or discontinue rewarded ads at any time.
Ad content is provided by third parties. We are not responsible for the products, services or websites of advertisers that you reach through an ad.
To show and measure ads, Google collects your device ID and advertising ID (ad ID), and may use them for tracking and personalised ads according to the choices you make. Details, and how to change those choices, are in the Privacy Policy.
7. Acceptable use
You agree not to: use the App for unlawful purposes; interfere with, reverse-engineer or disrupt the service; cheat, automate ad views or otherwise abuse rewards; or use the App to violate anyone's privacy — including your partner's.
8. Intellectual property
The App, the "Duoly - a couple app" brand, its interface and design assets belong to the developer. This does not affect your ownership of your content under section 4.
9. Disclaimer
The App is provided "as is". We work hard to keep the service stable but do not promise it will be uninterrupted or error-free. Suggested content (daily questions, AI suggestions) is for inspiration only and is not professional advice.
10. Limitation of liability
To the extent permitted by law, the developer's total liability for any claim related to the App will not exceed the amount you paid for the App in the preceding 12 months.
11. Termination
You may stop using the App and delete your account at any time, right in the App. We may suspend or terminate access for serious violations of these terms.
12. Changes
When these terms change materially, we will announce it in the App or on this page before it takes effect. Continued use after that date means you accept the new version.
13. Governing law and contact
These terms are governed by the laws of Vietnam. Questions: 1010creative.games@gmail.com.
