Privacy policy

Device control

YOYO discovers Android phones on the same Wi-Fi. You authorize wireless debugging pairing before control. Device names, connection details and pairing identities are stored on your controller. Screens and control operations travel between the selected phones over authenticated local connections; they are not uploaded to our subscription server. Only control phones you own or are authorized to manage.

Accessibility and other-app synchronization

This optional mode requires a separate in-app disclosure and your Android Accessibility authorization. While you enable synchronization, it identifies the foreground app and ordinary editable text to mirror your actions to paired, selected phones. Password fields are excluded from text reading. When you explicitly request self-pairing, wireless debugging pairing information is read temporarily to authorize the controller itself. Input text and pairing codes are not stored by our cloud service. Stop from the notification or the app; disable the service in Android settings.

Subscription and payment data

Our cloud subscription service processes a device-generated identifier, public verification key, purchase identifiers or tokens, payment status, expiry and a hashed recovery secret to verify membership, prevent duplicate grants and transfer membership on your request. Google Play handles purchases in the Google Play edition. Its Billing library also sends technical billing diagnostics to Google to operate and improve payment reliability. The independent edition uses Stripe and its available payment providers. We do not receive full card details. Payment providers process payment and account data under their own policies. Changing your phone language does not change your Play payment-account country. The price confirmed by the payment provider applies.

Service providers and network information

Cloudflare hosts subscription verification and may process request IP addresses, timestamps and security or operational logs. Stripe and Google process the data needed for their payment services. The independent edition may request a product-price reference quote; your input text and device screens are never included. We do not add advertising or behavioral analytics SDKs, sell personal data, or use control content for advertising.

Retention, deletion and your choices

Control credentials remain on your controller until removed or the app is uninstalled. Cloud subscription records are retained to provide verification and recovery and to handle payment records, security and disputes. Contact us to request access, correction or deletion; we verify requests and explain any records that must be retained. Never email pairing PINs, recovery codes, passwords or card details. Deleting the app does not cancel a subscription: cancel in Google Play or the Stripe subscription portal. Save your recovery code before uninstalling if you want to transfer membership.
