Privacy Policy

Who we are

NUTTR LLC (“NUTTR”, “we”, “us”) is a privately held company based in South Carolina, United States. This policy covers our website, nuttr.co, and the apps we publish. Stacks for iPhone and FITTR for iPhone and Apple Watch each have their own section below.

If you have a question about this policy, see Contact us below.

This website

nuttr.co is a simple, static website. It doesn’t use cookies, analytics, advertising, tracking pixels or third-party scripts, and it doesn’t load fonts or other files from other companies. It has no forms and no accounts.

Like every website, it is delivered by a hosting provider whose servers may automatically log technical details of each request, such as your IP address, browser type, the page requested and the time. Hosting providers use these logs to deliver the site and protect it from abuse. We don’t use them to identify or track visitors.

Email links on this site open your own email app. Nothing is sent to us unless you send it.

When you contact us

If you email us, we receive your email address, your message and anything you attach. We use them only to reply, to help with your question and to improve our apps and support. We keep correspondence for as long as it is useful for those purposes and for our business records, and then delete it.

Our email is stored by our email service provider on our behalf. You can ask us to delete your messages at any time.

Stacks

Stacks is an iPhone app that finds photos that look alike, picks the best photo and, when you choose, turns a moment into an Apple Photos burst. It is designed to do all of its work on your iPhone. Stacks doesn’t collect any data: nothing it reads or works out about your photos is sent to us or to anyone else.

Access to your photo library

Stacks asks for access to your photo library when you continue past its welcome screen. The only other permission it asks for is notifications, if you turn on the Weekly Reminder. It reads your photos and their details, such as the date and time each was taken, its location, whether it’s a favorite, which of your albums it’s in, and its caption, keywords and rating. It uses them to find moments and to carry those details over when you stack photos.

You can choose Full Access or Limited Access, and change or remove access at any time in the Settings app under Privacy & Security → Photos. With Limited Access, Stacks only sees the photos you’ve selected.

Analysis on your iPhone

To find moments, pick the best photo and fill Clean Up’s piles, Stacks analyzes your photos on your iPhone with Apple’s built-in tools. For each photo it looks at, Stacks keeps an analysis of the photo, such as how sharp it is and whether it shows people, a pet or a document. Stacks reads the text in some photos, such as documents and screenshots, on your iPhone and never keeps the text itself.

Scanning uses the copy of each photo that is already on your iPhone and never downloads photos from iCloud.

Face analysis

Many of the photos Stacks compares show people, so it also analyzes faces, on your iPhone, with Apple’s Vision and Core Image frameworks. For each face, Stacks keeps an analysis such as whether the person is smiling and whether their eyes are open.

Stacks uses this only to group photos into moments and pick the best one. It doesn’t try to identify who anyone is, and it doesn’t know or use names. Face data never leaves your iPhone and is never shared. It is stored only with the rest of the analysis described below, which is left out of backups and deleted when you delete the app.

What Stacks stores on your iPhone

Stacks keeps the following in its private storage on your iPhone. None of it is sent to us.

• Analysis. The analysis described above, including face data, plus a note of which photos are kept only in iCloud, so Stacks doesn’t have to redo its work every time you open it. These files are excluded from iCloud and computer backups. If you restore your iPhone or move to a new one, Stacks simply works them out again.
• A record of your stacks. So that each stack can be checked and undone, Stacks records, for every photo you stack, the details needed to check and restore each photo exactly: its original file name, date, location, favorite status, caption, keywords, rating, albums and Live Photo setting. It also notes which photos you marked to delete with the stack. This record is included in your iPhone’s backups (iCloud Backup or a backup on your computer, if you use them), so you can still undo your stacks after restoring your iPhone. Those backups are made and stored by Apple or on your own computer, under your settings, and we can’t access them.
• Settings and choices. Your settings, which photos you left out, which photo you picked as the cover photo, your swipes in a moment you haven’t finished, the photos you put in Kept or To Delete in Clean Up, which tips you’ve already seen, and all-time totals of photos deleted (with the space they took up) and moments stacked. These are kept in the app’s own storage on your iPhone, which is included in backups.
• Temporary copies. While stacking or unstacking, Stacks briefly writes copies of the photos involved to its temporary storage and removes them as soon as the step finishes.

Changes to your photo library

Scanning only reads your library. Stacks changes your library only when you ask it to. When you stack a moment, Stacks adds copies of the photos to your library as one burst, with the cover photo on top. Stacks then asks iOS to remove the separate originals. If a copy ever fails its check, Stacks asks iOS to delete the copies it just made, and your originals are left as they were.

Every deletion, whether from stacking, unstacking, Clean Up, Keep Best Photo Only, Delete All or Duplicates, needs your approval in iOS’s own confirmation, and deleted photos stay in Recently Deleted for 30 days.

Network connections and iCloud

Stacks makes no network connections of its own. It contains no networking code, and we check every release build to confirm that.

If you use iCloud Photos with Optimize iPhone Storage, some of your originals are kept in iCloud. When Stacks needs one, to show a sharper copy of a photo you’re looking at or to stack a photo whose original is only in iCloud, Stacks asks iOS, and iOS downloads the photo from Apple’s servers as it would for the Photos app.

When you share a new stack’s cover photo, Stacks hands a copy to iOS’s share sheet with the photo’s location removed, and you choose where it goes.

When you use Share Stats, Stacks makes a picture of your all-time totals on your iPhone and hands it to iOS’s share sheet with a link to try Stacks, and you choose where it goes.

Weekly Reminder

If you turn on the Weekly Reminder, Stacks lets you know on Sunday evening when there are new moments to sort. The notification is made on your iPhone. Nothing is sent to us, and no push service is used. It can show a new moment’s best photo, so that photo can appear on your Lock Screen. Stacks leaves out moments it sees as documents and photos kept only in iCloud. To count new moments, Stacks scans your library in the background when iOS allows, and only while the reminder is on. You can turn it off in Stacks’ Settings.

What Stacks doesn’t do

• No account or sign-in.
• No analytics, crash-reporting or advertising code, whether ours or another company’s.
• No tracking across apps or websites, and no use of the advertising identifier.
• No other permissions. Stacks doesn’t ask for your camera, microphone, contacts, location services or health data. It reads the location already saved in your photos, never your iPhone’s current location.

Your choices

• Change or remove Stacks’ access to your photos at any time in Settings → Privacy & Security → Photos.
• Delete Stacks to remove everything it stored on your iPhone: its analysis, its record of your stacks and its settings. Copies of the record and settings in existing backups remain until those backups are replaced or deleted.
• Deleting Stacks doesn’t remove your photos. Stacks you made stay in Apple Photos as ordinary bursts. Unstack anything you want as separate photos before deleting the app, because without its record Stacks can’t undo them later.

FITTR

FITTR is a lifting app for iPhone and Apple Watch, in development. It plans your workouts, records them on Apple Watch and shows your progress. FITTR doesn’t collect any data: nothing it reads or records is sent to us.

Apple Health

FITTR asks for access to Apple Health the first time you start a workout. Apple Health keeps one set of permissions for FITTR on your iPhone and Apple Watch, and you can change them at any time in Settings → Privacy & Security → Health → FITTR.

• What FITTR reads. Your heart rate, active calories and workouts, to show them during a workout, on its summary and in History. On Apple Watch, the distance you cover walking, running, cycling or swimming during a cardio part. On iPhone, last night’s sleep, heart rate variability (HRV) and resting heart rate, to show them against your usual range before you train.
• What FITTR saves. Each workout you record on Apple Watch, as Apple workouts, one for each part (for example, an elliptical warm-up, then strength training, then a cool-down), with the effort rating you give it, and for an outdoor walk or run, its route. FITTR keeps no copy of the route. Workouts imported from another app are never added to Apple Health.

FITTR reads last night’s sleep, HRV and resting heart rate each time it shows them, and doesn’t store them.

What FITTR stores

FITTR keeps your plans, workouts and sets, your settings, and the calories and average heart rate of each workout you record, in its own storage on your iPhone. This storage is included in your iPhone’s backups (iCloud Backup or a backup on your computer, if you use them). During a workout, your Apple Watch and iPhone share the workout, heart rate and calories over Apple’s connection between your devices.

iCloud Sync and network connections

iCloud Sync is on unless you turn it off in FITTR’s Settings. When it’s on, FITTR keeps your plans and workouts in sync through your own private iCloud database (Apple’s CloudKit). That data is stored in your iCloud account under Apple’s privacy policy, and we can’t see it.

Apart from iCloud Sync and Apple’s connection between your iPhone and Apple Watch, FITTR makes no network connections. It contains no networking code of its own.

Plans and Apple Intelligence

• Describe your goals. Apple Intelligence drafts a plan on your iPhone. What you type isn’t sent to us.
• Copy a prompt. FITTR copies a prompt with your goals to your clipboard. If you turn on Include My Recent Numbers, the prompt also includes some of your recent lifts. You choose where to paste the prompt, and that service’s own privacy policy applies.
• Paste a plan. FITTR reads only the text you paste in, on your iPhone.

Rest alerts and the Lock Screen

While Apple Watch records a workout, the watch taps your wrist when a rest is up. When the watch isn’t recording, FITTR can show a “Rest’s up” notification, scheduled on your iPhone with no push service, if you allow notifications. During a workout, a Live Activity shows the exercise, your next set and the rest countdown on your Lock Screen and in the Dynamic Island, where anyone who can see your iPhone can see them too.

Importing and exporting

Import from Fitbod and Restore from Backup read only the file you pick. Back Up Everything and Export Spreadsheet make a file only when you ask, and you choose where the file goes from the share sheet.

What FITTR doesn’t do

• No account or sign-in.
• No analytics, crash-reporting or advertising code, whether ours or another company’s.
• No tracking across apps or websites, and no use of the advertising identifier.
• No other permissions. FITTR doesn’t ask for your camera, microphone, contacts or photos, and asks for your location only to save the route of an outdoor walk or run.

Your choices

• Change what FITTR can read and save at any time in Settings → Privacy & Security → Health → FITTR.
• Turn iCloud Sync off in FITTR’s Settings to keep your data on your iPhone only.
• Delete FITTR to remove what it stored on your iPhone and Apple Watch. Workouts it saved to Apple Health stay there until you delete them in the Health app, and data synced to your iCloud stays until you delete it from your iCloud storage. Copies in existing backups remain until those backups are replaced or deleted.

Information handled by Apple

Our apps are distributed through Apple’s App Store and TestFlight. Apple handles the following under its own privacy policy, at apple.com/privacy.

• Downloads and purchases. Apple processes App Store downloads and any purchases, and never shares your payment details with us. We receive sales and download reports that don’t identify you.
• Crash reports and app analytics. If you’ve chosen to share analytics with app developers in your iPhone’s settings, Apple may share crash reports and usage statistics with us. They don’t identify you, and you can turn sharing off at any time in Settings → Privacy & Security → Analytics & Improvements.
• TestFlight. If you test a pre-release version of one of our apps, Apple shares with us the feedback and screenshots you choose to send, crash reports, and basic information such as your device model, iOS version and how often you open the app. If we invited you by email, we also have your name and email address. If you joined through a public link, Apple doesn’t share your name or email address with us. We use this only to improve the app.

Children

Our website and apps aren’t directed at children under 13, and we don’t knowingly collect personal information from children. Stacks and FITTR collect no personal information from anyone. If you believe a child has emailed us personal information, contact us and we’ll delete it.

Selling and sharing

We don’t sell, rent or trade personal information, and we don’t share it for advertising. We would disclose the little we hold, such as emails you’ve sent us, only if the law requires it.

Your rights

Depending on where you live, you may have the right to ask what personal information we hold about you, to correct it, or to have it deleted. In practice, we hold very little: mostly correspondence you’ve sent us. Contact us to make a request.

Changes to this policy

If we change how we handle information, we’ll update this page and its effective date. If a change is significant, such as an app beginning to collect data, we’ll explain it here before it takes effect.
