- camera brand, model and firmware version, and how you connect (Wi-Fi / Bluetooth / USB);
- the step where the problem appears, ideally with a screenshot or screen recording;
- for purchase issues, the store order ID. Never send passwords, one-time codes or payment details.
3. Frequently asked questions
Can I try it before buying?
Yes. Without a purchase you can explore the whole interface in demo mode; connecting a real camera requires the one-time unlock. You can also look up your camera under "Cameras" on this site.
How do I restore my purchase on a new phone?
For app-store purchases, sign in to the same store account on the new phone, open Zlens and tap "Restore purchase". One purchase can be active on up to 5 devices within any 30 days. A redeem-code unlock (directly distributed version) belongs to your Zlens account; just sign in again.
Can I get a refund?
No. Zlens is a one-time digital purchase: the unlock is delivered as soon as payment is confirmed and is not refunded afterwards, and there is no subscription to cancel. Purchases made through Google Play or the App Store are handled by the store under its own policy. A billing error such as a duplicate charge or a wrong amount is a different matter — write to us and we will verify and correct it.
How do I delete my account and data?
Confirm under Settings → Account → Delete account in the app, or ask us by email. What is deleted and what is kept is on the account deletion page.
Are my photos uploaded?
No. Photos and videos travel only between your phone and your camera; what our server does receive is listed in the privacy policy.
