Privacy Policy
Last updated: October 20, 2026
About this policy
This policy explains data handling in the Sidefolk app and on its website. Sidefolk is provided by Marcin Jędrzejak. For privacy questions, contact maartinjdev@gmail.com.
Conversations and on-device data
Sidefolk does not require an account. Conversations, agents, settings, and saved images are stored locally. In local mode, Apple’s model processes content on your device. The app does not send conversations to a developer server and contains no advertising or developer analytics tools.
Optional cloud processing (Private Cloud Compute)
Some agents can answer with Private Cloud Compute, Apple’s AI model running on Apple’s servers. Before anything is sent, the app shows a screen that explains what data is shared and with whom, and asks for your permission. If you tap “Don’t Allow”, every agent answers on your device only. You can withdraw permission at any time in Settings › Cloud Sharing. What is sent: your message, any photo you attach, and the data the agent’s skills read on your device to answer it — calendar events, reminders, contacts (names, phone numbers, email addresses, birthdays), and Health data (steps, sleep, workouts). Who receives it: only Apple Inc., through Private Cloud Compute. Sidefolk has no servers of its own and never receives this data. What it is used for: only to generate the reply. According to Apple, the data is not stored after the reply and is not accessible to Apple; Apple provides protection at least equal to the protection described in this policy. The data is never sold or used for advertising. This mode requires internet access. Apple describes its safeguards in the Private Cloud Compute documentation linked below.
Permissions and tools
Selected features can use contacts, calendars, reminders, the camera, photos, and Health data such as steps, sleep, and workouts. Access depends on the permissions you grant and the feature you use. Tools can create events and reminders; the Health integration is read-only. The data read is used to answer on your device; it reaches Private Cloud Compute only with your permission, as described above. You can change permissions in system settings. Health data is not used for advertising or marketing.
Purchases and support
Apple handles purchases and subscriptions. The app checks Pro access through StoreKit; the developer does not receive your card details. If you email me, I receive your address and message to respond and resolve your request. Please avoid sending sensitive information that is not needed for support.
Website data
The website saves your manually selected language and theme in browser local storage. Clear the site’s data to remove these preferences. The hosting provider may process technical data such as IP addresses, browser information, and page requests to deliver and secure the site. Apple and email links take you to separate services with their own privacy policies.
Retention and deletion
Local data remains on your device until you delete it in the app or remove the app. Device backups may retain earlier data according to your Apple settings. Events and reminders created in system apps must be deleted separately. I retain support correspondence as needed to handle the request and meet legal obligations or resolve a dispute.
Your rights and security
Where data protection law applies, you may request access, correction, deletion, restriction, or portability of data I process, and object or complain to a competent supervisory authority, including Poland’s UODO. Support processing is based on responding to your request and the legitimate interest in providing support; legal obligations may require retaining some data. I cannot access local conversations on your device. No storage or transmission method guarantees absolute security.
Children and policy updates
Sidefolk is not directed to children under 13. Follow the age restrictions shown in the App Store. If you believe a child provided personal data through support, contact me so I can delete it. Changes to the app or website may require updates to this policy; the current revision date appears above.
