Privacy Policy

Last updated 28 September 2026

The short version

Who is responsible for your data

BridgeSync is built and operated by Marcell Béres, an individual developer based in Hungary, acting as the data controller for the purposes of the UK and EU General Data Protection Regulation.

For any privacy question or request, write to support@bridgesyncapp.com. That address reaches the developer directly. If you need the controller's registered postal address for a formal regulatory request, it will be provided on request to that address.

What BridgeSync collects

BridgeSync collects the minimum needed to run an account across two devices. Everything below is tied to your account and nothing else is gathered in the background.

DataWhyLegal basis
E-mail address and password To create your account and sign you in on both devices. Passwords are stored only as a salted hash - they cannot be read, by me or anyone else. Contract
Your first name, last name and username Required at sign-up. They identify your account to you and label your devices across the app - there is no way to use BridgeSync without them. Contract
Date of birth Required at sign-up, for one reason: to confirm you are old enough to consent to an account yourself. See Age below. Legal obligation
Profile picture Genuinely optional, and the only thing here that is. Added after sign-up if you want one; the app is complete without it. Consent
Device name, model, battery level, online status, local network address, and each device's public encryption key So your iPhone and PC can find each other on your network, show whether the other one is reachable, and set up end-to-end encryption. The matching private keys never leave your devices. Contract
Transfer history: file names, file sizes, timestamps, which device sent or received, and a log of the PC commands you sent and your clipboard syncs To show your history and let you re-open a received file. File and clipboard contents are never included. Contract
App settings and preferences So your choices follow you between devices. Contract
Subscription status and purchase receipts To unlock Pro features and restore them on a new device. Handled by Apple and RevenueCat. Contract
Apple push notification token To wake the iPhone app when your PC needs to reach it. Contract
IP address and connection logs Seen by the hosting providers whenever your devices connect, and kept only in short-lived server logs for security and abuse prevention. Legitimate interest
Waitlist e-mail address (only if you joined the waitlist) To tell you when BridgeSync launches and to mark your account as a Founding User. Ask and it is deleted. Consent

What BridgeSync never collects

How your data is used

Only to operate the service. Specifically: to authenticate you, to pair your devices and keep them in sync, to show your history and settings, to unlock features you have paid for, and to answer your support requests.

Your data is never sold, rented, or shared for advertising, and it is not used to train machine-learning models.

Who else processes your data

A small number of service providers handle data on my behalf. Each is bound by a data-processing agreement and may only act on my instructions.

How long it is kept

Your rights

Under the GDPR you can, at any time:

E-mail support@bridgesyncapp.com and it will be handled within 30 days, free of charge. You also have the right to complain to your local data protection authority; in Hungary this is the Hungarian National Authority for Data Protection and Freedom of Information (NAIH).

Security

Connections to my servers use TLS. Passwords are stored as salted hashes. Access to the production database is restricted to the developer and protected by row-level security rules, so one account can never read another's data. Direct transfers between your devices stay on your local network and never traverse the public internet. Your files, clipboard and PC commands are end-to-end encrypted between your devices, with keys that are created on your devices and never leave them.

Age

BridgeSync is a utility and anyone can use it. This section is about who can hold an account, not about who is allowed to send a file.

Creating an account means handing over personal data, so you must be at least 13 to create one. In Hungary and much of the EU the age for agreeing to that on your own is 16, so if you are younger than that there, a parent or guardian has to agree first.

That is the entire reason your date of birth is required at sign-up. It is not used to profile you, it is not shared, and it drives nothing else in the app - it exists so the age rule above is actually enforced: the app will not create an account for anyone under 13. If you believe an account was created by a child without a guardian's consent, contact me and it will be deleted.

Changes to this policy

If this policy changes materially, the date at the top is updated and I will tell you by e-mail or in the app before the change takes effect. Continuing to use BridgeSync after that means you accept the revised policy.
