Please do not send passwords, card numbers or documents in an email. We will never ask you for them.
In apps that offer accounts, open Settings → Account → Delete account. The account is disabled immediately and everything associated with it is erased within 30 days. If you cannot reach that screen, write to hello@dayantech.com.br from the address on the account and we will do it for you.
Ask at hello@dayantech.com.br. We send a machine-readable export within 15 days, the deadline the Brazilian LGPD sets. There is no charge.
Subscriptions bought inside an iOS app are managed by Apple: open Settings → your name → Subscriptions on your device. On Android, open the Google Play Store, then Payments & subscriptions → Subscriptions. Cancelling stops the next renewal and you keep access until the end of the period you already paid for.
Purchases made through the App Store or Google Play are refunded by Apple or Google, not by us — use reportaproblem.apple.com or the Google Play order history. If you bought directly from us, write to hello@dayantech.com.br and we will handle it.
In our games with player sign-in, such as Runaway Paws, your progress lives in your own cloud, not on our servers. On iPhone, sign in to Game Center and keep iCloud turned on, with the same Apple ID as on the old phone. On Android, sign in to Google Play Games with the same account. Then open the game while online and wait a few seconds: the progress comes back by itself. Paid purchases come back under Shop → Restore purchases, with the same store account. Purchases and progress do not carry over from an iPhone to an Android phone, or the other way round.
The game checks your purchases every time it opens and delivers whatever is missing. Close the game and open it again while online. If it still has not arrived, tap Shop → Restore purchases. If something is still missing after that, write to hello@dayantech.com.br with the player identifier shown in the game profile (under Settings), the purchase date and the receipt from Apple or Google.
Some of our free apps show ads served by Google AdMob. To see only non-personalised ads, open Settings → Privacy options inside the app where that option is offered, or change your device settings: on iOS, Settings → Privacy & Security → Tracking; on Android, Settings → Google → Ads. Where the app offers a "remove ads" purchase, buying it stops the ads for good — use Restore purchases if they come back after reinstalling.
We confirm receipt within two business days, tell you whether we can reproduce it, and let you know which release will carry the fix. Crashes and data-loss bugs jump the queue.
Please report it privately to hello@dayantech.com.br with the subject line "Security", including the steps to reproduce it. We acknowledge within two business days and will keep you updated until it is resolved. Please give us a reasonable window to fix the issue before disclosing it publicly.
We answer in English, Portuguese and Spanish.
