Privacy Policy

What Iron Streak collects, how it's used, and the choices you have.

Last updated: October 30, 2026

This policy covers the Iron Streak app and website (ironstreakapp.com). "Iron Streak", "we" and "us" mean the developer of Iron Streak. Using Iron Streak is also covered by our Terms of Service.

The short version

  • We collect what you enter to use the app: your account details, workouts, food logs, bodyweight and settings.
  • We use it only to run Iron Streak for you. We don't sell it, show ads, or track you across other apps or websites.
  • AI Trainer messages, meal photos and descriptions, photos of food labels, and still frames from form-check videos are sent to our AI provider, Anthropic, to answer them, and only after you allow it in the app. We don't keep your AI Trainer conversations, meal or label photos, or videos.
  • The Feed is optional. What you post there (posts, photos, videos and reposts) is shared with your friends (or, if you make your account public, with anyone signed in to Iron Streak), your comments, likes and reposts also with anyone who can see the post they're on, and a direct message only with the person you send it to.
  • Showing your workouts or your streak to everyone on Iron Streak is off unless you turn it on, and nobody under 18 is ever shown. Your weekly workout counts are shared only with friends, and only while Compete with friends is on.
  • Photos and videos are edited on your device. Automatic video subtitles are made by speech recognition on your iPhone itself, so the sound isn't sent anywhere, and drafts stay on the device you saved them on.
  • Finding friends from your contacts is optional and happens on your phone: your contacts aren't uploaded. Only short codes made from their emails and phone numbers are sent, never names, and nothing is kept. Being found by people who have your email or number is off unless you turn it on.
  • A new profile photo is checked before others see it, by our AI provider or by a person on our team.
  • Community plans are optional too. A plan you share is shown to everyone signed in to Iron Streak, with your Feed name, username and photo. Paid plans are bought and sold through Stripe: we never see card or bank details.
  • Apple Health is optional and off unless you turn it on. Health data is never used for advertising or shared with anyone else.
  • Progress photos stay on your device unless you turn on backup, which keeps a private copy with your account that only you can see.
  • We keep daily backups of your app data for 30 days, so we can put it back if something goes wrong. They're deleted with your account.
  • You can export your data in Profile → Your data, and delete your account and all of its data at any time in Profile → Delete account.

1. Information we collect

Account information

Fitness, nutrition and body information you enter

Feed and messages (optional)

Community plans (optional)

Photo and video editing, the camera and drafts

AI Trainer usage

Subscriptions

Technical information

Health Connect (Android app, optional)

Apple Health (iPhone app, optional)

Apple Watch (optional)

Usage data and error reports. To fix bugs and improve the app, Iron Streak records which parts of the app get used (for example finishing the survey, logging a set, finishing a workout or opening Pro) and errors the app hits, with the app version and whether it's the iPhone app or the website. These records are linked to your account, kept in Iron Streak's own database (not a third-party analytics service), and used only by Iron Streak. You can turn this off any time in Profile → Your data → Share usage data.

Ad measurement (iPhone app). If you installed Iron Streak by tapping an ad (for example on TikTok), the app tells Apple's SKAdNetwork how far you've got, as a step number (such as made a plan, finished a workout or started a free trial). Apple passes that number on to the ad network later, without your name, account, device or anything you logged, so the ad can be measured without tracking you. For any other install, nothing is sent. Turning off Share usage data stops it too.

We don't collect your precise location or advertising identifiers, and your contacts are never uploaded (see Find friends from your contacts, above). There are no ads, no third-party analytics and no tracking across other companies' apps or websites in Iron Streak.

2. How we use your information

We don't sell your information, and we never use your fitness, nutrition or body information for advertising or marketing.

3. AI Trainer, form checks and meal photos

The first time you use the AI Trainer, a form check, Photo log or Describe your meal, the app tells you what it sends and to whom, and asks first. You can take that back any time in Profile → Your data → Share with the AI; the app then asks again before sending anything.

When you send a message to the AI Trainer, the app sends your message and your recent messages in that conversation, along with context from your account so the answer fits you. That context covers:

It doesn't include your name or email address. This information goes through our server to Anthropic, which writes the reply.

Once a week, from Monday morning to Wednesday, the AI Trainer offers a weekly check-in. When you open it, the app sends the same context as for a message, plus a summary of last week worked out on your device (workouts done and missed, sets and PRs, how many days you logged food and their average calories and protein, and your weigh-ins), and Anthropic writes the check-in. We keep a record of which weeks you've had one (the week and when), so there's one a week.

When you use Photo log, the photo you take or pick is resized on your device and sent through our server to Anthropic to estimate what's in it. If you fix an estimate with a note, the same photo is sent again with your note and the first estimate. When a barcode isn't found and you snap the package's nutrition label, that photo is sent the same way for the label to be read. When you use Describe your meal, the words you type are sent the same way. Nothing is logged or saved until you review and confirm it.

When you ask for a form check, the video you pick or record stays on your device: you pick one rep from it, the app takes 16 still frames from that part, resizes them, and sends only those frames, the lift's name, any note you add and your recent sets of that lift through our server to Anthropic, which describes your form. The video itself and its sound are never uploaded. Filming in the app records the picture only, without sound.

We don't store your AI Trainer conversations, meal or label photos, or form-check frames on our servers. Today's conversation (with small thumbnails of any form-check frames) is kept on your device so it's still there when you reopen the app, and a new one starts the next day; signing out or deleting your account removes it. Your form checks (the lift, the frames and the review) are also kept on your device only, as your form check history, so you can look back at them and compare them; they're never uploaded, and you can delete each one, or all of them with Reset all data or by deleting your account. Anthropic processes this content only to provide the service to us, and under its commercial terms it doesn't use content sent through its API to train its models. See Anthropic's privacy policy for details.

A new profile photo is made smaller on your device and kept privately (only you can see it) while it's checked: our server sends it to Anthropic, which says whether it fits the community rules. One that does goes on your profile; one it isn't sure of waits, still private, for Iron Streak's founder or a moderator to approve or reject it, and a rejected one is deleted. On an iPhone whose Sensitive Content Warning or Communication Safety is on, Apple's own check on your iPhone looks at it first, and nothing is sent for a photo it flags.

AI answers can be wrong, and a form check from a few still frames can miss things or misjudge them. It isn't medical advice. Nothing the AI Trainer suggests changes your data until you approve it.

4. Who we share it with

We share information only with the service providers that run Iron Streak for us, and only what they need:

Other Iron Streak users. If you use the Feed, your friends see your Feed profile (name, @username, profile photo and streak, your best lifts and Top PRs, and the medals you've earned), your posts, photos, videos and reposts (with their captions, subtitles, the friends tagged in them and any workout you added), and the bot's posts for you. Friends you tag or @mention in a post see that you did, in their Activity and in a notification if they've turned them on; only friends can be tagged or told about a mention. Anyone who sees a post can see its comments and how many likes and reposts it has, and the people behind them. When a friend reposts or sends one of your posts, the people they share it with can see that post too. Someone with a pending friend request with you can see your Feed profile. Anyone signed in can find you by your name or username, and Iron Streak may suggest you to friends of your friends and to people who started a plan you shared, showing your name, username, photo and streak; Feed options → Let people find me turns this off (friends can always find you, and blocking works either way). People under 18 aren't shown in searches or suggestions, except to friends of their friends. A direct message is seen only by you and the person you send it to. Anyone signed in with a Feed profile can send you a message request, friend or not: one message, in words only, until you reply. People under 18 can message only their friends. Blocking stops both. People you have messages with can see your name, username, photo and streak. If something is reported, Iron Streak's founder and the moderators the founder chooses can see it, including a reported message, to review it. A post, comment, account or community plan that three people report is hidden until it's reviewed: an account shows as “Member”, without its name, username or photo, and a plan leaves Community lifts. People who have your email or number in their contacts can find you only if you turn that on, as above. Friends can save photos and videos you post; saved copies carry an Iron Streak label.

Competing with friends. While Compete with friends is on, friends who have it on too see how many workouts you've finished and sets you've done this week against your plan, whether you've trained today, your buddy streak with them, and where your best set on a lift ranks among theirs; and they can nudge you after 5 PM on a day you have a workout planned (once a day each, which sends you a notification if you have them on). When your bot posts a PR or a medal, your friends can get a notification about it. Turn Compete with friends off and you're left out of all of it.

Everyone on Iron Streak. If you turn on Show my workouts to everyone, the bot's workout recaps from today (the workout's name, how many lifts and sets, how long it took, its PRs and any medal) are shown to everyone signed in to Iron Streak, with your name, username and photo. If you turn on Show my streak on Top streaks, your streak is shown the same way when it's among the longest. Both are off unless you turn them on, turning one off takes you out at once, and people under 18 are never shown, whatever they choose. Each weekly challenge shows how many people have earned its medal, as a number, without names.

Public accounts and following. Your account is private unless you turn on Public account on your Feed profile (it isn't available to people under 18, and an account that's suspended counts as private). While it's on, anyone signed in to Iron Streak who hasn't blocked you can see your Feed profile and your own posts, as friends do, with their likes, comments and reposts, and can like, comment on and repost them; your reposts of other people's posts still go only to your friends. They can also follow you, with no friend request: your posts then show in their Feed. Everyone can see how many followers you have; only you see who follows you, and people under 18 who follow you aren't listed by name unless you're friends. When you follow someone, they can see that you follow them, in their Activity and in a notification if they've turned them on, unless you're under 18. Every account follows Iron Streak's own account (@ironstreak) to start with; you can unfollow it. Turning Public account off makes your posts friends-only again. You can unfollow anyone, remove a follower, and blocking someone ends any follow between you.

Workout recaps. The bot's recap of each workout shows the workout's lifts and the weight and reps of each set to everyone who can see the post. They can copy that workout into their own plan; nothing of theirs is shared with you when they do.

If you have Iron Streak Pro and a Feed profile, a Pro badge shows on your profile to anyone who can see it. Nothing else about your subscription is shown.

Posts Iron Streak's founder makes in Founder mode are shown to everyone signed in to Iron Streak. If you like or comment on one, everyone who can see the post can see your comment, with your name and photo.

A community plan you share is shown to everyone signed in to Iron Streak (unless one of you has blocked the other), with your Feed name, username and photo, its outline and how many people have used it. Its lifts, sets and reps are shown to people who start it, or who buy it if it costs money. Buying a paid plan is a payment to its creator's own Stripe account, so the creator can see that payment in Stripe, including the name and email address given at checkout. In the app, creators see how many people viewed, started and bought each of their plans (and how many purchases came through their own link) and what they earned, not who. A paid plan's first training day is shown in full to anyone who can see the plan. When you ask for a refund, the plan's creator sees your request (the reason, your note, the price and the dates), not your name. Everyone signed in sees each plan's average rating and how many ratings it has, not who gave them. A review you write is shown, with your stars and your Feed name, username and photo, to everyone who can see the plan (unless one of you has blocked the other); one by someone under 18 is shown only to their friends. A creator bio and the Instagram or TikTok usernames you add are shown with your plans and on your Feed profile to everyone who can see them, never for someone under 18. Anyone signed in who opens your profile link (ironstreakapp.com/u/your-username) can see your name, photo and streak, and send you a friend request. Anyone else who opens that link sees a web page with your name and profile photo, not your streak or anything else, and only while Feed options → Let people find me is on, you're 18 or over and your account isn't suspended; otherwise the page shows just your username. These pages are kept out of search engines. A link to a community plan you shared (ironstreakapp.com/p/…) shows anyone who opens it the plan's title, description, price and your username. Your invite link (your profile link with your invite code, or its QR code) makes whoever joins with it your friend right away, for the first 10 people within 30 days of the link; after that, or once you make a new link, it sends you a friend request instead. With anyone under 18, it's always a friend request to accept. People you invited who are new to Iron Streak see that you invited them, and you see their name, photo and how many of their first 2 workouts they've finished.

We may also disclose information if the law requires it, or to protect the rights, safety and security of our users or others. If Iron Streak is ever transferred to a new owner, your information would transfer with it and remain covered by this policy.

5. Photos

Your profile photo is stored at a web address that isn't published or listed anywhere, but anyone who has that exact address can view the photo. Only use a profile photo you're comfortable with others seeing. A new one is kept privately until it's been checked, as described in section 3.

Photos and videos you post to the Feed or send in a message are stored privately. The app shows them through links that expire within an hour, and only to the people allowed to see them, as described above.

Progress photos you add on the Weight page stay on your device unless you turn on Back up to your account there. With backup on, a copy of each is stored privately with your account, where only you can see it (not your friends, not anyone else), so a new phone signed in to your account gets them back. Deleting a photo deletes its copy; turning backup off deletes all the copies; resetting your data or deleting your account deletes them too, and the photos on that device. Each account can keep up to 60 backed-up photos.

6. How long we keep it

We keep your account and app data until you delete it or delete your account. When you delete your account, we delete your login, profile, profile photo (and any new one waiting for its check), backed-up progress photos, the codes for being found from contacts, the age range Apple shared, app data and its backups, AI Trainer message counts and AI usage totals, and subscription status, and your Feed profile, friends, follows, posts, photos, videos, comments, likes, reposts, messages (from both sides of each conversation) and notification tokens, and your community plans, your ratings, reviews, plan views, creator bio and refund requests, and the link to your Stripe account (the Stripe account itself is yours, with Stripe). Signing out removes that device's notification token. A plan someone bought can be hidden but not deleted, so its buyers keep it, until you delete your account. Records of purchases are kept for tax and accounting, without the account once it's deleted. Deleting a post or unsending a message removes it for everyone. Reports may be kept as long as needed to keep the Feed safe. Deleting your account doesn't cancel your subscription: Apple keeps billing it until you cancel it in your iPhone's Settings. Our service providers may keep request logs and backups for a limited time under their own policies.

Backups. Your app data (your plan, workouts, food log, weights, measurements and settings) is copied to a backup each day it changes, so that if it's lost or saved over, for example by another device, we can put it back as it was on any of the last 30 days. Only we can see the backups, and we use them only to put your data back: when you ask us to, or to fix a problem on our side. We delete the ones we no longer need to cover those 30 days, and deleting your account deletes them all. Backed-up progress photos (section 5) are kept separately, not in these backups.

7. Your choices and rights

8. Security

Your data travels over encrypted connections (HTTPS). Our database only lets each account read and change its own data, and our secret keys stay on our server, never in the app. No system is perfectly secure, but we work to protect your information.

9. Children

Iron Streak isn't meant for children under 13, and we don't knowingly collect personal information from them. If you believe a child under 13 has given us information, contact us and we'll delete it.

10. Where your data is processed

Our service providers may process and store information in the United States and other countries, whose data protection laws may differ from those where you live.

11. Not medical advice

Iron Streak is for general fitness and information only and isn't medical advice. Check with a healthcare professional before starting a new exercise or nutrition program.

12. Changes to this policy

We may update this policy from time to time. When we do, we'll change the date at the top, and for significant changes we'll let you know in the app or on this page.
