App privacy
The Grzybiarz app is designed so that your data stays with you. Here are the key principles.
Works offline: detection, recognition, and maps run without a network.
On-device models: photos are processed on your phone and are not sent to a server.
Local finds: your foraging trips and routes stay in your device’s storage.
GPX export: you can export your own copy of the data at any time.
No tracking: we use no tracking pixels and no advertising profiling. Visit statistics cover the website only, and only if you agree to them.
Contributing to model training (optional)
If you turn this on in settings, your photos of confirmed finds can be used to train the recognition model. This is a separate, optional consent, independent of whether a find is private or public. Photos have their location stripped (EXIF/GPS), and you can withdraw consent anytime. After you withdraw it, we delete your contributed photos from the training data. This option is off by default.
Website visit statistics (cookies)
This part covers the grzybiarz.app website only, not the app on your phone. If you agree to statistics, we use Google Analytics 4 to see which texts you read and where you get lost. Consent is optional: without it the site works exactly the same.
We keep your decision in the browser (localStorage, key "grzybiarz-consent"). It is not a cookie, it never leaves your device, and it exists only so we do not ask you twice.
After consent, Google Analytics sets its own cookies (_ga and _ga_*) that recognise repeat visits from the same browser.
We collect the address of the page you opened, an approximate location derived from your IP address (country and city, without storing the full IP), your device and browser type, and where you came from.
We never use this data for advertising or remarketing, and we do not link it to any account in the app.
Legal basis and withdrawing consent
Statistics run on your consent alone (Art. 6(1)(a) GDPR). Until you give it, we load no Google script and send nothing to it. You can withdraw at any time: "Cookie preferences" in the site footer or Settings in the web version. Withdrawal stops the sending immediately, with no page reload.
Recipient and transfers outside the EEA
Statistics are run by Google Ireland Limited, and data may also be processed by Google LLC in the USA under the European Commission adequacy decision (EU-U.S. Data Privacy Framework) and standard contractual clauses. How long events are kept follows the data-retention setting in Google Analytics (2 to 14 months).
Privacy policy: beta test
This policy describes how we process the data you provide in the Grzybiarz beta-test signup form. It covers only the testers list, not your use of the app itself (which runs offline, on your device).
Data controller
The data controller is [business name], [address], tax ID [___], email: kontakt@grzybiarz.app. (Fill in before publishing.)
What we collect
Email address, to send the confirmation link and the test invitation.
Platform (Android / iOS), to assign you to the right test track.
Name (optional), only if you provide it, to personalize messages.
Date and version of the consent given, for accountability (GDPR).
Technical data: a hash of your IP address and your browser header, solely for abuse prevention. We do not store the raw IP address.
Purpose and legal basis
We process the data based on your consent (Art. 6(1)(a) GDPR) in order to invite you to the beta test and communicate about it. You may withdraw consent at any time.
Recipients
We use Resend (Resend, Inc.) as a processor to deliver emails. Data is stored on our own server (EU).
Retention period
We keep the data until the beta-test program ends or until you withdraw consent, whichever comes first. After that it is deleted.
Your rights
You have the right to access, rectify, erase, restrict processing of your data, and to withdraw consent. To exercise these rights, email kontakt@grzybiarz.app.
