Privacy Policy
Effective May 2026
Overview
Deltify is built on a simple principle: your workout data belongs to you, and stays on your device. We don't run servers, we don't sell ads, and we don't have user accounts. This page describes what data the app handles and how.
What Deltify stores
As you use the app, Deltify creates and keeps a local record of:
- Workout sessions you log (exercise, reps, duration, timestamp, and optional notes)
- Exercise selections from the built-in catalog
- Equipment preferences you set in the Equipment screen
All of this is stored exclusively on your iPhone or iPad using Apple's SwiftData framework. It is never transmitted to a Deltify server or shared with any third party.
What Deltify does not collect
Deltify does not collect, request, or transmit:
- Personal information — no name, email, phone number, or address
- Account credentials — no sign-up, no login, no user ID
- Location data
- Contacts, photos, health data, or other personal records
- Device identifiers used for advertising or tracking
- Usage analytics, crash reports, or behavioral metrics
Local storage only
Deltify has no cloud component. Your data lives in a SwiftData database file on your device and goes nowhere else. We do not operate any sync service or remote backup.
If you have iCloud Backup enabled at the system level, Apple may include the app's local data as part of its standard device backup — that's a service between you and Apple, and is outside Deltify's control.
No third-party analytics or sharing
Deltify contains no third-party analytics SDKs, advertising networks, or tracking pixels. The app does not share any data with any third party, because no data ever leaves your device in the first place.
Deleting your data
Because everything is stored locally, you are always in control:
- Individual workout sessions can be removed from the History screen by swiping to delete.
- To remove all Deltify data, uninstall the app from your device. iOS deletes the app's local database when it removes the app.
Children's privacy
Deltify is intended for general audiences and does not knowingly collect personal information from anyone, including children under 13. Because the app collects no personally identifiable information of any kind, there is no data about any individual user to retain or disclose.
Changes to this policy
If this policy is updated, the revised version will be posted at this URL with a new effective date. Material changes will be reflected in the app's release notes.
