Most issues come down to one of a handful of root causes. Try the relevant section below before writing in — it'll usually get you back to a working transfer faster.
Transfers
The recipient never sees my offer
- Confirm the four-digit code matches exactly. Codes are case-insensitive but every digit counts.
- Make sure the receiving device has filester open and is online (green dot in the top bar).
- If you've signed in on multiple devices, the recipient code routes to the device that last refreshed it. Open filester on the device you actually want to receive on.
Transfer is stuck or extremely slow
- Both peers need a stable connection. Mobile data with weak signal often stalls WebRTC.
- Restrictive corporate or hotel networks sometimes block direct UDP. filester will fall back to a TURN relay, which is slower but still end-to-end encrypted.
- For very large files on Firefox or Safari web, use the iOS or Android app — those browsers buffer received files in memory.
Transfer fails near the end
- Check available storage on the receiving device. Large files need room to finalize.
- Keep the screen awake until the progress reaches 100%. Some operating systems aggressively suspend background apps.
Device codes
Each device advertises a short numeric code. You can copy the code, share the QR, or rotate it from the receive tab. Pro accounts can reserve a vanity code.
- Rerolling a code immediately invalidates the previous one — useful if you accidentally shared it with the wrong person.
- If you sign in, your code follows your account. Sign out to fall back to a guest code.
Pro subscription
How do I restore a purchase on a new device?
Sign in to filester with the same account you used to purchase. Pro restores automatically from the App Store or Google Play receipt via RevenueCat.
How do I cancel?
- iOS: Settings → your name → Subscriptions → filester → Cancel.
- Android: Play Store → Profile → Payments & subscriptions → Subscriptions → filester → Cancel.
Cancelling stops the next renewal. You keep Pro until the end of the current billing period.
Refunds
Refund requests are handled by Apple or Google under their respective policies. Use reportaproblem.apple.com for Apple purchases, or the Play Store order history for Google.
Account
I can't sign in
- If you signed up with Apple or Google, use the same provider — accounts aren't merged across providers.
- For email/password, use "Reset password" on the sign-in screen. Check your spam folder if the reset email doesn't arrive within a few minutes.
I want to delete my account
Email [email protected] from the address tied to your account. We'll confirm and process the deletion within 30 days, including any subscription state held with our payments provider.
Contact us
Still stuck? Email [email protected]. It helps if you include:
- What you were trying to do (send, receive, sign in, etc.).
- The device and OS version on both ends.
- The approximate time the issue happened, so we can correlate with broker logs.
- The four-digit code only if you're comfortable sharing it — we can usually help without it.
