Terms of Use

ExtraSense mobile application · Last updated: 17 August 2026

These terms are the agreement between you and RoBk — "we", "us" — the independent developer who publishes ExtraSense, about your use of the ExtraSense mobile game on Google Play and on the App Store. RoBk is a trading name of an individual developer, not a company; the developer's verified legal name and contact address are shown on the app's page in the store you installed it from. By installing or using ExtraSense you accept them. If you do not accept them, do not use the app.

1. What ExtraSense is

ExtraSense is a collection of small games about guessing hidden things. It is entertainment. The games are built on chance, and nothing in the app is a measurement, a diagnosis, a prediction, or a statement about anyone's abilities. Scores, streaks and the "against chance" figures shown after a session are part of the game and mean nothing outside it.

2. Your licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use ExtraSense on devices you own or control, for your own non-commercial entertainment, in line with the rules of the store you installed it from. We keep all other rights.

You agree not to:

• copy, sell, rent, sub-licence or redistribute the app or any part of it;
• reverse engineer, decompile or disassemble it, except where that right cannot lawfully be excluded;
• modify the app or use tools to alter progress, unlock paid content, or interfere with advertising;
• use the app in any way that breaks the law where you are.

3. Age

You must be at least 13 years old, or the minimum age required in your country to agree to terms like these, to use ExtraSense. If you are under the age of majority where you live, a parent or guardian must agree to these terms on your behalf.

4. Advertising

ExtraSense is free and shows a small number of adverts. When you first open the app we ask whether adverts may be chosen using your device's advertising identifier; you can change your answer at any time in Settings, and refusing costs you nothing — the same games and the same number of adverts. What the advertising provider processes, and how to opt out at the operating-system level, is described in our Privacy Policy.

Adverts come from third parties. We do not control what they contain and we are not responsible for advertised products, services or websites.

Some games are part of Pro. You may also open one of them for a single run by choosing to watch a video advert, a limited number of times per day. That is an offer, not a requirement: no video is ever shown unless you ask for it, and if the video does not finish, nothing is used up and nothing is unlocked.

5. ExtraSense Pro: purchases and subscriptions

ExtraSense Pro unlocks additional games and settings and removes all advertising. It is offered as an auto-renewing subscription of 3 or 12 months, or as a single permanent purchase.

• Price and billing. The price, the length of the period and the amount charged are shown on the purchase screen before you confirm, in your own currency. Payment is taken by Apple or Google through your store account.
• Renewal. A subscription renews automatically at the same price at the end of each period unless you cancel it at least 24 hours before that period ends. The permanent purchase does not renew and is charged once.
• Cancelling. You can cancel at any time in your store account — on iOS, Settings → your name → Subscriptions; on Android, Google Play → Payments & subscriptions. The "Manage subscription" link on the purchase screen takes you straight there. Cancelling stops the next renewal; Pro stays active until the end of the period you have paid for.
• Refunds. Refunds are handled by Apple and Google under their own policies, not by us. Where the law gives you a right of withdrawal — for example the 14-day right in the EU — that right stands, and the store is where you exercise it.
• Restoring. "Restore a purchase" on the purchase screen brings Pro back on a new device or after reinstalling, using the store account that bought it.

Because payment runs through the store, your store's own terms also apply to the transaction. On iOS, unless we say otherwise, Apple's standard Licensed Application End User Licence Agreement applies alongside these terms; where the two conflict, these terms govern anything they cover.

6. Your data

ExtraSense has no accounts and no server of ours. Your settings and progress live on your device and are deleted when you uninstall. What is stored, what the advertising provider processes, and how to exercise your rights is set out in our Privacy Policy, which forms part of these terms.

Because progress is stored only on your device, uninstalling the app, clearing its data or losing the device loses that progress. There is no backup we can restore from. A Pro purchase is not lost: it lives with your store account and comes back with "Restore a purchase".

7. Changes to the app

We may add, change or remove games, modes and features, and we may change what is included in Pro in future versions. If a change would remove something you have already paid for during a period you have paid for, we will not apply it to that period.

8. No warranty

ExtraSense is provided "as is" and "as available". To the extent the law allows, we make no warranty that it will be uninterrupted, error-free, or fit for any particular purpose. Nothing here removes rights you have as a consumer under the law of your country, including any statutory guarantees that cannot be excluded.

9. Limitation of liability

To the extent the law allows, we are not liable for indirect or consequential loss, lost data or lost progress arising from your use of ExtraSense. Where liability cannot be excluded, it is limited to the amount you paid us for the app in the twelve months before the claim. Nothing here limits liability for death, personal injury, fraud, or anything else that cannot lawfully be limited.

10. Ending this agreement

You can end it at any time by uninstalling the app. We may suspend or end your licence if you break these terms in a material way. Sections 8 and 9 survive.

11. Apple and Google

Apple and Google are not parties to these terms and are not responsible for ExtraSense or its content. They have no obligation to provide support for it. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.
