Privacy Policy

This policy explains what data the BayMobil mobile app (iOS and Android), developed by Baykom Bilgisayar ve Yazılım Teknolojileri LTD. ŞTİ. (“Baykom”), processes, for what purposes, and how.

1. How the app works

BayMobil is a business app that lets employees of companies using LOGO ERP (the “Company”) handle orders, invoices, shipments, stock and warehouse operations from a mobile device. The app can only be used by people whose Company holds a BayMobil license and whose device has been activated by the Company. No user accounts are created in the app; users are defined in the Company’s LOGO system.

2. Your Company’s data

Business data you see and enter in the app (accounts, orders, invoices, stock, stock counts, etc.) and your LOGO user information are processed and stored on your Company’s own server and in its LOGO database. Your Company is the data controller for this data. Baykom does not store, view or analyze it, and the app does not store it permanently on the device.

The app first connects to the server on your Company’s local network. If that server cannot be reached, data is forwarded to your Company’s server through Baykom’s relay server (“Relay”) over an encrypted connection (HTTPS/TLS). The Relay only passes data through; it does not record or log the content. Screens loaded from the Company server use only first-party cookies needed to keep your session; no tracking or advertising cookies are used.

3. Data processed by Baykom

For licensing and security purposes, only the following device information is processed:

Device identifier: A random identifier generated by the app on first launch. It is not a hardware identifier or an advertising identifier.
Device information: Device name, operating system (iOS / Android) and app version. The device name may include the name you set in your device settings.
License records: Which Company the device belongs to, activation date, last connection time and device revocation records.
Device key: A public key generated to verify the device’s identity. The private key stays in the device’s secure storage and never leaves the device.

This information is used to link the device to your Company’s license, enforce the license quota and prevent unauthorized access. Legal basis: performance of a contract and legitimate interest (Turkish Personal Data Protection Law, KVKK, Art. 5/2-c and f). For server security, connection IP addresses may be kept in temporary technical logs.

The short-lived session key received during activation and the server addresses to connect to are kept only in the device’s encrypted secure storage.

4. Camera

The camera is used only to scan barcodes, and only when you start a scan. Camera images are not saved or sent anywhere; only the scanned barcode number is used for the relevant operation. You can turn off camera access at any time in your device settings.

When you share a report or statement (PDF, Excel), the file is created temporarily on the device and the operating system’s share sheet opens. You choose where the file is sent; the privacy terms of the app you choose (e.g. email, messaging) apply.

6. Data we do not collect

BayMobil does not access location, contacts, photo library, microphone or health data. It does not use advertising, analytics, crash reporting or tracking tools, and it does not track users across other apps or websites. Your data is not sold to third parties or shared for advertising.

Device information is shown only to your Company’s authorized administrators, in Baykom’s license portal, for license management. It is not shared with anyone else unless required by law. Our servers are located in Turkey.

8. Retention and deletion

Device records are kept for the duration of the license and any legal retention obligations, and are deleted within a reasonable time after the license ends or the device is revoked. Technical connection logs are kept only as long as needed for security.

When you delete the app, the identifier, keys and session information on the device are deleted as well. When your Company administrator revokes a device’s license, that device can no longer connect. You can request deletion of your device record from your Company’s BayMobil administrator or at kvkk@baymobil.com.tr.

9. Your rights

Under Article 11 of the KVKK, you have the right to learn whether your data is processed, to request information, and to request correction or deletion. For device data processed by Baykom, contact kvkk@baymobil.com.tr. For data on your Company’s server, contact your Company.

10. Children’s privacy

BayMobil is a business app for company employees and is not directed at anyone under 18.
