The controller within the meaning of this policy is the developer of the app, Bartosz Kołek, contact: bartosz@ikolek.pl.
- The app does not collect personal data and does not send it to the developer. There are no user accounts and no developer server.
- Data (invoices, payment files, bank statements, templates, settings) is stored on the user’s device and protected by iOS file encryption.
- The KSeF token is stored only in the device’s Keychain and is not included in backups or in iCloud.
- If the user has iCloud Drive turned on, the app saves a copy of the data in the user’s private iCloud. The developer has no access to it.
- If the user adds a reminder, the app saves it in the iOS Reminders app. Access to Reminders is used solely to create, edit and check off reminders created by the app.
- The app connects only to:
- the API of the National e-Invoice System (KSeF, Polish Ministry of Finance) — to download and send invoices at the user’s request;
- the API of the Register of VAT Taxpayers (the “White List”, Polish Ministry of Finance, wl-api.mf.gov.pl) — when the user enters the tax ID (NIP) of a buyer or of their own company to fill in the name and address (automatically when those fields are empty, or with a button); only that tax ID and the current date are sent;
- the App Store — tip purchases are handled by Apple.
- The app does not use advertising, analytics or tracking. The website ksefektywnie.ikolek.pl does not use cookies or analytics tools.
- Reports sent with the “Report a problem” button are sent from the user’s Mail app to bartosz@ikolek.pl; they contain only what the user writes in them, plus the app version, the iOS version, the device model, the interface language and the KSeF environment (test or production). The developer uses them solely to reply and to improve the app.
- Changes to this policy will be published on this page with a new effective date.
- Contact: bartosz@ikolek.pl.
