Privacy Policy

Last updated: September 27, 2026

Slowfold is a breathing companion for iPhone and iPad, made by Gimlet Tannery. It is a relaxation tool — not a medical device. This page describes the data our advertising and analytics partners collect when you use the app, how it is used, and what stays on your device. It matches the App Privacy information on the App Store page for Slowfold.

Data collected — used to track you

Slowfold includes the Adjust attribution SDK and the AppLovin MAX advertising SDK. Our partners collect the categories below and may use them to track you across other companies’ apps and websites:

• Device identifiers (Device ID) — linked to you. Purposes: analytics, app functionality, developer’s advertising, third-party advertising.
• Advertising data (Advertising Data) — linked to you. Purposes: analytics, developer’s advertising, third-party advertising.
• Product interaction (Product Interaction) — linked to you. Purposes: analytics, app functionality, developer’s advertising, third-party advertising.
• Coarse location (Coarse Location) — linked to you. Derived from your network address at country/region or city level; never precise location. Purposes: analytics, app functionality, developer’s advertising, third-party advertising.
• Other data (Other Data) — linked to you. A catch-all category declared by the integrated SDKs. Purposes: analytics, app functionality, developer’s advertising, third-party advertising.
• User identifiers (User ID) — linked to you. Purpose: third-party advertising.
• Performance data (Performance Data) — not linked to you. Purposes: analytics, app functionality, developer’s advertising, third-party advertising.

Data collected — not used to track you

• Crash data (Crash Data) — not linked to you. Purpose: analytics.
• Other diagnostic data (Other Diagnostic Data) — not linked to you. Purposes: analytics, app functionality, developer’s advertising, third-party advertising.

“Used to track you” means the data may be shared with third parties for advertising measurement or to link you with other companies’ apps, websites or services. “Linked to you” means the data is connected to your identity (for example a device identifier); “not linked to you” means it is not.

Who collects it

• Adjust — attribution and analytics. See the Adjust privacy policy.
• AppLovin MAX — advertising mediation. MAX connects apps with multiple third-party advertising networks; those networks may collect the categories above as well. See the AppLovin privacy policy.

App Tracking Transparency (iOS)

The first time the app launches, iOS asks whether you allow Slowfold to track your activity across other companies’ apps and websites. If you allow it, advertising partners may use device identifiers for personalised advertising and measurement. If you ask the app not to track, that personalised use is limited — the app keeps working either way. You can change your choice at any time in iOS Settings → Privacy & Security → Tracking.

What stays on your device

To show your streak and recent sessions, Slowfold keeps a small file inside the app’s private storage on your device. It holds:

• the date of each session (no time of day), the rhythm you used and how long you practised;
• your settings, such as theme, sound cues, haptics and reminder time.

This file is not part of any of the data categories listed above. It never leaves your device, and neither we nor our partners receive it.

Daily reminder

If you switch on the optional daily reminder, iOS asks for permission to show notifications. The reminder is scheduled locally on your device; nothing is sent to a server. You can turn it off in the app’s Settings or in iOS Settings at any time.

Deleting your data

Open Settings → About → Reset all data in the app to clear your history and settings. Deleting the app also removes everything it stored. Data already collected by advertising and analytics partners is handled under their own privacy policies.

Children

Slowfold is suitable for all ages. We do not knowingly collect personal data from children beyond the categories described above.

Changes

If this policy changes, the updated version will be posted on this page with a new date.
