Sharp Eye Privacy Policy
- You can play without signing in. If you do, your progress is saved only on your phone and nothing about your games is sent to us.
- If you connect a Solana wallet, we save your public wallet address with your XP, level, best scores, daily streak and daily challenge scores on our server. Progress you made on your phone before connecting moves to your wallet profile.
- We never see your private keys or recovery phrase, and we never ask you to send a transaction or move funds.
- Your wallet address, XP and scores can be viewed publicly (for example, on the in-app leaderboards).
- We don't sell your data, show ads, or use analytics or tracking tools.
1. Who we are
Sharp Eye is a set of casual games (Colour, Shape Challenge and Don't Tap) for Android. This policy explains what information the app uses, why, and the choices you have. "We", "us" and "our" mean the developer of Sharp Eye.
2. Information we collect
If you play without connecting a wallet
Your XP, level, best scores, daily streak and daily challenge result are saved only on your device (see section 6). Nothing about your games is sent to us.
If you connect a Solana wallet
Connecting is optional. When you connect, your wallet app asks you to sign a short sign-in message. Signing is free, is not a blockchain transaction, and only proves that you control the wallet. Any progress saved on your device is then sent to our server, added to your wallet profile and removed from your device. We store:
| Information | Why we use it |
|---|---|
| Your public wallet address | To identify your player profile. It is also shown in the app as your player name. |
| XP, level, best score for each game, and number of games played | To save your progress, show your level and rank, and keep your best scores. |
| Your daily streak and the date you last finished a game | To count how many days in a row you have played and give the streak bonus. |
| Your daily challenge score, the date and which game it was | To allow one try per day and show the daily challenge leaderboard. |
| Your XP and best scores for each week | To show the weekly leaderboard. |
| Date and time your profile was created and last updated | To run and maintain the service. |
| A random session code | To keep you signed in. It is stored on your device and on our server. |
| A one-time sign-in code | To check your signature. It is deleted as soon as it is used. |
We do not collect your name, email address, phone number, contacts, photos, location, private keys, recovery phrase or wallet balances.
Technical information
When the app talks to our server, our hosting provider may automatically log basic technical details such as your IP address, the time of the request and error information. These logs are used only to keep the service running and secure.
3. Public information
Your wallet address, XP, level, best scores, weekly scores and daily challenge scores are readable by anyone who uses our public game data, for example on the in-app leaderboards. Wallet addresses on Solana are already public by design, but linking one to your game progress makes that progress visible to others. If you don't want this, play without connecting a wallet.
4. How we share information
We do not sell, rent or trade your information, and we don't use it for advertising. We only share it:
- With our service provider: we use Supabase to host our database and server code. Supabase processes data on our behalf.
- Publicly: as described in section 3.
- When you choose to share: if you tap Share after reaching a new rank, the app creates an image of your badge and rank on your device and passes it, with a short message, to the app you pick (for example a messaging or social app). We don't receive it. That app's own privacy policy applies to what you share there.
- If required by law: or to protect the rights, safety and security of our users and the service.
5. Wallet apps and the blockchain
The wallet app you choose (for example Seed Vault Wallet, Phantom, Solflare or Jupiter) is provided by another company and has its own privacy policy. Sharp Eye does not write anything to the Solana blockchain. Your XP, level and scores are kept only on our server. They are not tokens or NFTs and have no money value.
6. Information stored on your device
The app stores on your device:
- If you play without connecting a wallet: the app saves your progress on your phone so it's still there next time you open the app. This includes your XP, best score in each game, number of games played, daily streak and today's daily challenge score. It is not sent to us.
- the date you last started the daily challenge, so it can only be played once a day;
- the theme, badge frame and title you picked on the Style screen;
- if you connect a wallet: your wallet address and session code, so you stay signed in.
This information is not sent to us, except progress that moves to your wallet profile when you connect (section 2). Tapping Disconnect removes your wallet address and session code from your device; your saved progress stays on our server so you can connect again later. Uninstalling the app or clearing its data removes everything stored on your device, including progress made without a wallet.
7. How long we keep information
We keep your player profile, daily challenge scores and weekly scores for as long as the service runs, or until you ask us to delete them. Sign-in codes are deleted when used or when they expire. Server logs are kept for a limited time by our hosting provider.
8. Your choices and rights
- Play without a wallet: your progress stays on your device and is never sent to us.
- Disconnect: you can disconnect your wallet in the app at any time.
- Access or delete your data: email us at zihui001@hotmail.com with your wallet address. We will delete your profile, scores (including daily and weekly scores) and sessions. We may ask you to sign a message to confirm the wallet is yours.
Depending on where you live, you may have extra rights under local law, such as the right to object to processing or to complain to a data protection authority.
9. Security
We use encrypted connections (HTTPS), check wallet signatures on our server, and restrict who can change stored data. No method of storage or transmission is completely secure, so we can't guarantee absolute security. Keep your wallet and device secure, and never share your recovery phrase with anyone, including us.
10. Children's privacy
Sharp Eye is not directed at children under 13, and wallet sign-in is intended for users old enough to use a crypto wallet where they live. We do not knowingly collect information from children. If you believe a child has connected a wallet, contact us and we will delete the related profile.
11. International users
Our service provider may store and process data in countries other than your own. We take reasonable steps to protect your information wherever it is processed.
12. Changes to this policy
We may update this policy from time to time. We will post the new version on this page and change the "Last updated" date. If the changes are significant, we may also tell you in the app.
