1. Terms of Use
These terms apply to every app, game, website and course published by ZyeemZia™, including the ZBZGames™ titles and the ZyeemZia™ Academy. Each app and game on Google Play also has its own terms of service, listed in the Policy Directory below, which take priority for that product. Anything you obtain through Google Play is also covered by Google Play's terms.
- Fair use: use our products lawfully and for their intended purpose. Do not attempt to break their security, interfere with the services behind them, copy them at scale, or pass them off as your own.
- Reference tools: navigation, coordinate, abbreviation, calculation and planning features are aids only. Always cross-check with approved maps, instruments, official publications and your organisation's procedures before relying on a result.
- No affiliation: our products are independent. They are not affiliated with, endorsed by or connected to any government, armed force, ministry or alliance, or to any other certifying body.
- Purchases: in-app purchases and subscriptions are processed by Google Play Billing under Google Play's terms, including its refund policy. We never see your payment details.
- As is: our products are provided "as is" and "as available". To the extent permitted by law, we give no warranty that they will be error-free or uninterrupted, and we are not liable for indirect or consequential loss arising from their use.
- Changes: we may update, improve or retire features at any time, and we may update these terms. The date at the end of this page shows when they last changed.
- Governing law: these terms are governed by the laws of the People's Republic of Bangladesh.
2. Privacy Principles
We collect as little as possible, keep it on your device wherever we can, and say plainly when anything leaves it. Each product's own privacy policy (see the directory below) lists exactly what that product uses.
- On your device first: our apps work without accounts. Documents, routes, waypoints, scores, settings and progress stay on your device unless you choose to share or export them.
- Location: apps that use GPS process it on your device. Location is only used by an online service when you choose a feature that needs one, such as live map tiles or a multiplayer tournament, as each app's policy explains.
- Advertising: some free apps and games show ads from Google AdMob, which can also deliver ads from Meta Audience Network through mediation. Both may receive your device's advertising ID and basic device and ad interaction data. Where the law requires it, you are asked for consent before personalised ads are shown, and you can opt out of personalised ads in your device settings at any time.
- No selling of personal data: we do not sell personal data, and we never ask for biometric or identity documents.
- Websites: zyeemzia.com and its sub-sites use no advertising or analytics cookies. Messages you send through the Direct Transmission Hub are delivered by FormSubmit to our inbox. The Academy course sites keep progress in your browser, run the official exam on our own server, and offer optional Google sign-in to sync progress.
- Your rights: you can ask us to access, correct or delete personal data we hold about you, or object to its use, by contacting us. Most data never reaches us, so you can usually delete it yourself on your device.
- Children: our products are not directed at children under 13 (or 16 in certain jurisdictions). Learners under 13 should use the Academy with a parent or guardian.

4. Intellectual Property
The software, designs, code, artwork, course content and other material published under the ZyeemZia™ and ZBZGames™ names belong to Zyeem Bin Zia, unless a third-party licence says otherwise.
The ZyeemZia™ and ZBZGames™ names, logos and product titles are used as trademarks. Please do not copy, redistribute or reverse engineer our products, or use our brands in a way that suggests a connection that does not exist. We act on infringements through the platforms concerned.
5. Security and Store Compliance
Our apps are built to follow the Google Play Developer Program Policies. They request only the permissions their features need, explain each one in their privacy policy, and keep data on the device wherever possible. Connections to online services are encrypted.
If you find a security issue in any of our products, please report it privately to [email protected] so we can fix it before it is made public.
