Privacy Policy

Effective: September 30, 2026 · Last updated: October 2, 2026

This Privacy Policy explains how information is handled by the Mantle app for iPhone and Apple Watch (including its widgets, watch complications and Live Activities), the mantlefit.app website, our support email, and our social media accounts. Mantle is developed by Andrew Parrish, a sole proprietor based in Houston, Texas ("we", "us").

Residents of Washington, Nevada and Connecticut, and anyone interested in how Mantle handles health-related data, should also read our separate Consumer Health Data Privacy Policy.

1. Summary

We do not operate a server that receives your training data, and there is no Mantle account.
Your training data is stored on your devices. iCloud sync is on by default: it copies Mantle's records to your private iCloud database, which Apple runs and we cannot access. You can turn it off in the Rig (Mantle's settings).
Apple Health is used only with your permission. On Apple Watch, Mantle reads your heart rate and active energy during a session and shows your heart rate on screen. Mantle does not store those readings itself or send them anywhere.
Information can leave your device through Apple services, device backups, links you open, and text you choose to share. Section 7 lists each route.
The only personal information we receive is what you send us, such as support emails, and reports Apple provides to developers. Section 8 lists them.
No third-party ads, no third-party analytics, no tracking, and no sale of personal data.

2. Does Mantle collect your data?

Apple's App Store privacy labels treat data as "collected" when it is sent off the device in a way that lets the developer or its partners access it beyond what is needed to handle a request in real time. By that definition, the Mantle app does not collect data: nothing the app handles is sent to us or to any company working for us.

That does not mean your data never leaves your device. It can go to your own iCloud account, to Apple Health, into your device backups, and to places you choose (Section 7). Those destinations are controlled by you and Apple, not by us. Separately, we do receive information you choose to send us and reports Apple provides (Section 8).

3. Information stored on your devices

Mantle keeps its data in the app's own storage on your iPhone and, for the watch app, on your Apple Watch, so it works offline. This includes:

Training records: each session's sets, targets, repetitions or hold times, duration and date, your grade, your baseline and Final Test results, and whether the session was saved to Apple Health.
Program progress: your dig sites, week and day, pauses, Endless Dig progress, relics and trophies.
Claims (dig sites you build): the name, the movement name and the optional safety note you type, and the goal, unit and other choices you pick.
Settings: your display name, your companion's name, theme, sound and haptics, training days, reminder time, Save to Apple Health, iCloud sync, Game Center, and your Pass status as reported by Apple.

Mantle does not access your camera, microphone, location or contacts, and does not use an advertising identifier.

4. iCloud sync (on by default)

If your iPhone is signed in to iCloud, Mantle's iCloud sync is on unless you turn it off. It uses Apple's CloudKit to store copies of Mantle's records in the private database of your own iCloud account, so your devices stay in step. We do not have access to your private iCloud database.

What syncs: training records, dig-site progress, Claims (including the names and notes you typed), and some settings: relics found, weekly outcomes, whether you have seen the introduction, training days, whether reminders are on, reminder time and your current dig site.
What does not sync through Mantle: your display name, your companion's name, theme, sound and haptics, the Save to Apple Health, iCloud sync and Game Center settings, and your purchases. No Apple Health data is copied into Mantle's iCloud records. Only a yes-or-no marker showing whether a session was saved to Health syncs.
Turning it off: open the Rig and turn off iCloud sync. That stops future syncing. It does not delete copies already in iCloud (see Section 13).
Sync notifications: to learn that your data changed on another device, Mantle receives silent notifications from Apple's push notification service. They are sent by Apple's iCloud service. We do not run a push server and Mantle does not send us a device token.

5. Apple Health

5.1 Save to Apple Health. Mantle's Save to Apple Health setting in the Rig is off by default. Apple shows its own permission screen, where you choose each type of data Mantle may read or write. You can change those choices at any time in Apple's Health settings.

5.2 On iPhone. Mantle does not read any Health data on iPhone. When Save to Apple Health is on, Mantle writes each completed session to Apple Health as a "Traditional Strength Training" workout, with an active energy value and these workout details: the brand name "Mantle", the exercise name (for a Claim, the movement name you typed) and the total repetitions. Apple attaches information about the device that recorded the workout. The active energy value is estimated by Mantle from a formula based on session time and repetitions. It is not measured.

5.3 On Apple Watch. The first time you start a session on the watch, it asks permission to read heart rate and active energy and to write workouts and active energy. For every session you run on the watch, if Apple Health is available and you have allowed Mantle to save workouts, Mantle starts an Apple Watch workout session, whether or not Save to Apple Health is on, and reads your heart rate and active energy while the session runs. If not, the session runs without an Apple Watch workout session and no Health data is read. Mantle shows your heart rate on screen. The readings are held only in the watch app's memory and cleared when the session ends. Mantle does not write them to its own storage, send them to your iPhone, or sync them to iCloud.

If Save to Apple Health is on, the watch saves the session to Apple Health as a "Functional Strength Training" workout, together with the heart rate and active energy recorded during it.
If Save to Apple Health is off, the watch discards the workout when the session ends and nothing is saved to Apple Health.
If the watch cannot save the workout (for example, a session longer than the app's logging limit, or a failed save), your iPhone saves a Traditional Strength Training workout with estimated active energy and no heart rate, if Save to Apple Health is on.

5.4 Where Health data lives. Data in Apple Health is stored and protected by Apple under your control. If you have turned on Health in iCloud, Apple syncs Health data as part of its own service.

5.5 Our commitments for Health data. We use information from Apple Health, and information Mantle writes to it, only to provide Mantle's health and fitness features to you. We do not use it for advertising, marketing or data mining. We do not sell it. We do not disclose it to any third party without your express consent. In practice, Mantle never sends Health data to us at all.

6. Other features that use your information on your devices

iPhone and Apple Watch: the two apps exchange session plans and results directly between your paired devices. Plans include dig-site and exercise names (for a Claim, the names you typed). Results include targets, repetitions, timing and a random session ID. They do not include heart rate, energy or device identifiers.
Widgets and watch complications: Mantle writes a small summary (current dig-site name, session and week progress, pause state, last workout time, training days and reminder time, and for watch complications also your current streak, last session total and rest-timer state) into a shared container on the device so widgets and complications can display it. This summary stays on the device and is excluded from device backups.
Live Activities: during a session, the Lock Screen and, on supported iPhones, the Dynamic Island show the dig-site name and set progress. The Live Activity runs locally. It uses no push token.
Notifications: Mantle asks for notification permission after your first logged session, or when you switch on Session Reminders in the Rig. It schedules local notifications on your iPhone: training-day reminders, return reminders after a quiet period, which name your dig site (for a Claim, the name you typed), holiday greetings, which may use your display name and your companion's name, and notices when you unearth a relic. They are created on your device, not sent by us. Their text can appear on your Lock Screen, depending on your notification settings. The silent iCloud sync notifications are described in Section 4.
Handoff: Mantle lets your other Apple devices offer to open its Quarry or Today screen. Only the screen's title is shared, through Apple's Handoff between devices signed in to your Apple Account. It is not added to search.
Photos (add-only): if you save a magma wallpaper for your Apple Watch face, Mantle asks for add-only access and adds that image, which is Mantle artwork, to your library. Mantle cannot see your photos.
Game Center (Mantle 1.0.6 and later): Game Center is Apple's gaming service. Mantle's Game Center setting in the Rig is off by default, and nothing is sent to Game Center unless you turn it on. When it is on and you are signed in to Game Center on your iPhone, Mantle reports your achievements to it: for each achievement, only its identifier and how far you are toward it as a percentage. Mantle works these out on your device from your own records (sessions saved, trophies, relics, your training streak, and similar milestones). It does not send your training records, Apple Health data, display name, companion name or Claim text to Game Center, and it does not store or send us your Game Center name or player ID. When you turn it on and are not signed in, Apple may show its own Game Center sign-in screen. Apple shows your achievements to you in the Games app and Game Center, may show them to other players according to your Game Center settings, and shows everyone what share of players earned each achievement. Apple handles Game Center under its own privacy policy. Turning the setting off in the Rig stops Mantle reporting and discards any reports waiting to be sent. Achievements Apple already holds stay with Apple (see Section 13).
Purchases: Apple processes purchases, renewals, refunds and restores. Mantle checks your Pass status with Apple's purchase system on your device. We do not receive your payment details or your Apple Account identity.

7. When information leaves your device

Your iCloud account, when iCloud sync is on (Section 4).
Apple Health, when Save to Apple Health is on (Section 5), and Apple's Health sync if you use it.
Device backups. Most of Mantle's data is included in your device and iCloud backups. Some files are excluded: an in-progress session draft, sync bookkeeping, device preferences (such as your display name and Save to Apple Health setting) and your most recent sessions until they are folded into the main log.
Links you open. "Watch video examples" opens a YouTube search for the exercise name followed by "proper form tutorial". For a Claim, that is the movement name you typed. Relic pages can open a YouTube search for the relic's name with added geology search terms. Research links open articles on PubMed, PubMed Central, doi.org and other cited websites. When you tap a link, that site or app receives your request and handles it under its own privacy policy.
Text you share. The share button opens Apple's share sheet with a short message with your display name and the dig-site name (for a Claim, the name you typed), and usually your session or weekly volume, plus hashtags. It goes only where you choose to send it.
Handoff to your own devices (Section 6).
Game Center, only if you turn its setting on and are signed in: achievement progress only (Section 6).
Purchases through Apple (Section 6).
Emails you send us (Section 8).

8. Information we receive

This is everything we receive. We do not combine these sources to build a profile of you.

8.1 Support emails. If you email mantleapp@icloud.com, we receive your email address, your name if you include it, your message, and any attachments or device details you send. We use them to reply to you, fix problems and keep a record of the conversation. Our mailbox is an Apple iCloud Mail account, so support emails may be stored by Apple, including in the United States. We keep a support conversation for up to 24 months after its last message, then delete it, unless we need it longer to deal with a legal claim. We will delete it sooner if you ask. Please do not send health details unless they are needed to answer your question.

8.2 GitHub. Our GitHub repository is private, so we do not take reports there. Please email us instead.

8.3 App analytics and crash reports from Apple. If you have chosen in your device's privacy settings to share analytics with app developers, Apple provides us with app usage information and crash reports from your device. We see usage information in App Store Connect in aggregated form, and crash reports as technical logs. We use them only to understand how Mantle is used overall and to fix bugs, and not to identify anyone. You can turn this sharing off in your device's privacy settings.

8.4 Sales and subscription reports from Apple. Apple gives developers reports of purchases, trials, renewals, cancellations and refunds, grouped by product and country. We use them for business, accounting and tax purposes. They do not tell us who you are.

8.5 Beta testing. If you test a pre-release version through Apple's TestFlight, we receive the email address used for your invitation and any feedback, screenshots or crash reports you choose to send through TestFlight. We use them only to improve Mantle.

9. How we use information

We use the information in Section 8 only to answer you, provide support, fix and improve Mantle, understand overall usage, keep business, accounting and tax records, and meet legal obligations. We do not use it for advertising, and we do not use health or fitness information for marketing or data mining.

10. Sharing, sale and advertising

No sale. We do not sell personal data, including sensitive data and health data.
No targeted advertising. We do not share personal data for cross-context behavioral or targeted advertising. Mantle has no third-party advertising, no third-party analytics or crash-reporting tools, and no tracking. It contains no third-party code libraries.
No third parties in the app. The app shares no user data with third parties. The only services involved in the information we receive are Apple (iCloud Mail, App Store Connect and TestFlight) and GitHub (website hosting). They handle it under their own privacy policies.
Legal requirements. We may disclose information we hold, such as a support email, if the law requires it or to protect someone's safety or rights. We do not hold your training data, so we have none to disclose.
If Mantle changes hands. If we transfer Mantle to a new owner, support records may transfer with it. The new owner must follow this policy or tell you about changes as Section 19 describes.

11. The mantlefit.app website

This website is hosted by GitHub Pages. GitHub may log visitors' IP addresses and other request information under its own privacy statement. The site has no cookies, analytics, advertising pixels or trackers, and it stores nothing in your browser. It runs two small scripts of its own: one line that tells the page scripts are on, and one file that animates the page, counts down to the next video episode and plays the episodes. Neither sends anything anywhere. Everything the site loads, including its fonts, images and videos, comes from mantlefit.app itself. The “Add all six to my calendar” button builds the calendar file on your device. Links to Apple, GitHub and other sites take you to those sites, whose own policies apply.

12. Social media

If you follow, comment on or message Mantle's social media accounts, the platform (for example TikTok, Instagram or YouTube) handles that information under its own privacy policy, and we can see what the platform shows to account owners, such as your public profile and comments. If we use a social media management tool to schedule posts or read comments and messages on our accounts, that tool processes the same information on our behalf. We use it only to run our accounts and respond to you.

If we advertise Mantle on a platform such as Facebook or Instagram, that platform decides who sees the ad under its own policies and gives us only aggregate results, such as how many people saw or tapped it. Neither the app nor this website contains an advertising pixel or software development kit, so we do not send any platform information about what you do in Mantle or on this site.

13. Retention and deletion

Mantle keeps its data until you delete it. Because we do not hold your training data, you delete it with these controls:

On a device: delete the Mantle app. This removes its data from that device. Copies in existing device backups remain until those backups are deleted or replaced.
In iCloud: turn off iCloud sync in the Rig to stop future syncing. Mantle has no button that deletes its iCloud data. If Apple lists Mantle in your iCloud storage settings (on iPhone, under Settings, your name, iCloud; the exact menu depends on your iOS version), you can delete its iCloud data there. Deleting a Claim in Mantle while sync is on also removes that Claim from iCloud.
In Apple Health: delete Mantle workouts and energy samples in the Health app. To stop access, change Mantle's permissions in Apple's Health settings.
Device backups: delete old iCloud or computer backups in your device's iCloud settings or on your computer.
Photos: delete saved wallpapers in the Photos app. To remove access, change Mantle's Photos permission in Settings, Privacy & Security, Photos.
Notifications: the Rig's reminder switch turns off training-day reminders. To stop all Mantle notifications (return reminders, holiday greetings, relic notices), turn off notifications for Mantle in Settings.
Support emails: email us and we will delete your conversation (Section 8.1).
Game Center: turn off Game Center in the Rig to stop Mantle reporting achievements. Achievements already reported are held by Apple. To manage them or sign out, use Game Center in your iPhone's Settings, or contact Apple.
Purchases: purchase history stays with Apple. Cancel subscriptions in your Apple Account settings.

Mantle has no account, so there is no account to delete. We cannot remotely delete data in your devices, iCloud account or Apple Health, because only you and Apple control them.

14. Security

Mantle's data files on your iPhone and Apple Watch are protected by iOS and watchOS file protection, which keeps them encrypted until you first unlock the device after it restarts. Data in iCloud and Apple Health is secured by Apple. Keep a passcode on your devices and keep your Apple Account secure. Our support mailbox is an Apple iCloud Mail account. No method of storage or transmission is completely secure.

15. Children

Mantle is a general-audience fitness app for people 13 and older. It is not directed to children under 13, and we do not knowingly collect personal information from children under 13. Mantle's App Store age rating describes its content, for example that it has no mature content. It is not a statement that Mantle is designed for young children. If you believe a child under 13 has sent us personal information, for example by email, contact us and we will delete it.

16. Your choices and rights

You control the data Mantle handles through the settings in Sections 4, 5 and 13. For information we hold (Section 8), you can ask us to confirm what we have, give you a copy, correct it, or delete it, by emailing mantleapp@icloud.com. We will not treat you differently for making a request. If we decline a request, we will explain why, and you can appeal by replying with "Appeal" in the subject line. We will answer an appeal in writing. If you are not satisfied, you can contact the privacy regulator or attorney general where you live.

17. United States state notices

California. The personal information we receive is described in Section 8, and the only services involved are listed in Section 10. You can review and ask us to change or delete it as Section 16 describes. We do not sell or share personal information, and we do not disclose personal information to third parties for their direct marketing purposes.

Do Not Track. Mantle and this website do not track you over time or across other companies' apps or websites, and we do not allow other parties to do so through them. Because there is no tracking, we do not respond differently to Do Not Track signals. When you open a link to another website from Mantle or this site, that website's own practices apply.

Texas. We do not sell personal data, including sensitive data.

Washington, Nevada and Connecticut. See our Consumer Health Data Privacy Policy.

18. Canada

18.1 Person in charge. The person responsible for the protection of personal information, and to whom complaints and questions should be sent, is Andrew Parrish, Owner and Privacy Officer, at mantleapp@icloud.com, +1 281-206-4074, or 529 Barker Clodine Rd, Apt 15208, Houston, TX 77084.

18.2 What we hold. The personal information we hold is described in Section 8. The Mantle app does not send us personal information. We do not share personal information with related organizations, because there are none.

18.3 Storage outside Canada and Québec. Support emails are received in the United States in an Apple iCloud Mail account, which may be stored by Apple, including in the United States, and may be subject to United States law.

18.4 Governance practices. Andrew Parrish is the only person who handles personal information for Mantle. Support emails are kept only as long as Section 8.1 states and are then deleted from the mailbox and its deleted-items folder. We do not use technology that identifies, locates or profiles you. If a privacy incident ever involves information we hold, we will assess it, contain it, keep a record of it, and notify affected people and regulators where the law requires.

18.5 Your rights. You can ask to access or correct the personal information we hold about you, and you can withdraw your consent to our use of it. Email us, and we will respond within 30 days. You can also complain to the Office of the Privacy Commissioner of Canada or, in Québec, to the Commission d'accès à l'information.

19. Changes to this policy

We will update this policy when Mantle's practices change, and change the "Last updated" date at the top. For a material change, we will post the new policy here and give notice through the app (for example, an in-app message or the release notes of an app update) before the change takes effect. If a change would let us receive new kinds of personal information, or use it in a new way, we will ask for your consent where the law requires.
