Privacy policy

Who we are

Volu(me) is made and published by Yaroslav Lopanskiy, an independent developer. “We” and “us” on this page mean the developer.

What the app collects

Nothing. Volu(me) has no account, no sign-up and no login. The app talks to no server of ours or of anyone else: its only network traffic goes through Apple’s own services, for the features below (the App Store for purchases, and your own iCloud Drive if you turn sync on). It contains no analytics or crash-reporting libraries, no advertising and no third-party code. We do not know who uses the app, how often, or what they log.

If you have turned on Share With App Developers (Settings › Privacy & Security › Analytics & Improvements), Apple may pass us anonymous crash reports and usage statistics for the app. That is Apple’s setting and applies to every app on your iPhone; Volu(me) itself sends nothing.

Where your data is

Everything you enter (your plan, workouts, sessions, custom exercises, notes, tracked lifts and settings) is stored on your iPhone in the app’s own storage. It stays there unless you choose one of the following.

Backup to Files. You can save a full backup as a JSON file to the Files app at any time. The file is yours: it goes wherever you put it, and we never see it. Restoring from a backup file is part of Pro.

iCloud Backup & Sync (Pro, off by default). If you turn on Sync with iCloud in Settings › iCloud Backup & Sync, the app writes your data to its own folder in your iCloud Drive (Files › iCloud Drive › Volu(me)). The folder holds one sync file, Volu(me) Sync.json, which every iPhone signed in to your Apple Account reads and adds to, one previous copy of it, and one dated backup for each day you train, of which the newest ten are kept. So that a session you delete does not come back from another iPhone, the sync file also lists the IDs and dates of deleted sessions and notes for 90 days. Apple stores these files in your Apple Account, and we cannot read them. Apple’s iCloud terms and privacy policy apply to them. Sync and the daily backups stop when you turn the switch off or when Pro ends. Neither of those, and not Erase all data in the app either, deletes the files: they stay in iCloud Drive until you delete them in the Files app.

Apple Health (Pro, off by default). If you turn on Apple Health in Settings and allow it in Health’s own permission sheet, the app writes one workout to Health for each session you finish on that iPhone: its start time, its end time, its activity type (such as strength training or running) a random identifier that links it to the session, and the iPhone it was saved on, as Health records for every app. It writes no calories and no sets, and it asks for no permission to read anything from Health. Sessions that arrive through iCloud Backup & Sync or from a backup file are not written. Once a workout is in Health, the app never changes or deletes it: editing or deleting a session changes it in Volu(me) only, and the workouts in Health are yours to manage in the Health app. The app reads nothing from Health, so nothing from Health goes into your iCloud Drive through Volu(me).

Siri and Shortcuts (Pro). Siri and Shortcuts hand your request to the app on your iPhone, and the app carries it out there. So that Siri can recognise a workout by its name, the app gives the system the names of the workouts in your plan and the muscle groups each one trains. Siri’s answers, such as your next workout or how many sessions you did this week, are worked out on your iPhone and shown or spoken by Siri. Apple processes voice requests under its own Siri privacy terms. Nothing is sent to us.

Purchases

Volu(me) Pro is sold through Apple’s App Store using StoreKit. Apple processes the payment and holds the receipt. We do not receive your name, address, card details or Apple Account information. Managing or cancelling a subscription happens in your Apple Account settings.

Notifications

The rest-timer notification and the lock-screen timer are created on your iPhone. No push service is involved, and iCloud Backup & Sync does not use one either: the app reads the sync file when you open it and after each session.

This website

The site stores your language choice in your own browser (a cookie named volu_lang). It identifies nothing about you and is not used for any other purpose. The site loads no analytics script. It is served by Cloudflare, whose servers see the technical details of every request (IP address, browser type) as any web host does and show us aggregate traffic counts; Cloudflare’s privacy policy applies to that.

Children

The app is not directed at children under 13 and collects no data from anyone.

Changes

If this policy changes, the new version appears on this page with a new date at the top. Because the app collects nothing, changes are expected to be rare and small.
