Privacy Policy
The short version
FitnessFeed lets you share health numbers with friends, and you decide what gets shared. Here is what that means in practice:
- Your health data starts in Apple Health on your phone. Only what you choose to share leaves it, at the level you choose.
- Friends see only what you share with them. Nobody else can see it.
- Progress photos are private until you share a specific one.
- We don't sell your information, and your health data is never used for advertising.
- You can delete your account inside the app at any time, and your information goes with it.
The rest of this page explains each of these in detail.
Who we are and how to reach us
FitnessFeed is made by Derrick Michael Guthier, an individual developer. In this policy, "we" means Derrick Michael Guthier.
For any question, request, or concern about your privacy, email privacy@fitnessfeed.net.
What we collect
This table lists every kind of information FitnessFeed keeps, why, and where it lives. "Our servers" means the hosting service we use, described under "Who can see what."

Your health data
Your health data stays on your phone unless you choose to share it, and you control each kind separately.
What we read from Apple Health. With your permission, FitnessFeed reads your weight, height, date of birth, biological sex, food and nutrition, active energy, exercise minutes, workouts, sleep, and steps. Weight and nutrition you log inside FitnessFeed are saved back to Apple Health. You can change or withdraw this permission any time in your iPhone's Settings.
What leaves your phone. For each kind of data, you pick a sharing level, such as "off," "trend only," or "exact." The app works out the version you chose to share and sends only that. Your sleep score is calculated on your phone. If you set something to "off," nothing about it is sent.
Changing your mind. When you lower a sharing level or turn something off, the app replaces what we hold with the new, smaller version the next time it sends an update, so friends stop seeing the old value.
Challenges. If you join a challenge, the app sends your daily score for that challenge's measure (for example, steps) for the days the challenge runs.
What we never do with it. We don't use Apple Health data for advertising or marketing. We don't sell it, and we don't share it with advertisers, data brokers, or insurers.
The calorie coach. The coach works out your target on your phone. The details it uses, and your plan, are not sent to our servers.
Meal names and saved meals. Names you give your meals are saved with the entry in Apple Health on your phone. Meals you save so you can log them again are kept on your phone and, if you use iCloud, in your own iCloud account. We never receive them, and friends never see them.
Food search and barcode scanning. The camera is used only on your phone, to read a barcode. Pictures are not saved or sent anywhere. The words you search for, or the number in a barcode you scan, go to our server, which asks USDA FoodData Central for nutrition information. We do not store what you search for or scan.
Progress photos
Progress photos are private by default. Only you can see a photo until you decide to share that specific photo.
- Saving. Photos are resized on your phone, and location and other hidden details are removed before upload. They are kept in private storage that only you can open.
- Sharing. When you share a photo, it appears in the Milestones feed of all your current friends, who can like and comment on it. By default, friends see it blurred until they tap it.
- Stopping. Tap "Stop sharing" and friends lose access to the photo. Delete a photo and its files are removed from our servers, along with any post that shared it.
- A limit we can't remove. Anyone who can see a photo you share could take a screenshot of it. Please share only what you are comfortable with.
- What we do with photos. We use them only to show them as you direct. We don't analyze them or use them to train machine-learning models.
Photos are for people 18 and older.
Who can see what
| Who | What they can see |
|---|---|
| Your friends | Only the health numbers, goal details, and photos you choose to share, at the levels you set, plus the posts you make |
| Anyone signed in to FitnessFeed | Your display name and username, so they can find you and send a friend request. Nothing else |
| People in a challenge with you | Your name and your daily score for that challenge |
| People you block | Nothing. They can't see your updates, send you requests, or comment on your posts, and they are not told |
| Our hosting provider | The information stored on our servers, only to run the service for us |
| Apple | What Apple already handles: Apple Health on your phone, and the App Store and TestFlight |
Service providers. We use Supabase to host our database, sign-in, and private file storage, in the United States (East US, North Virginia). We use an email service to send account emails such as password resets. When you search for a food or scan a barcode, our server asks the U.S. Department of Agriculture's FoodData Central database for nutrition information. USDA receives the search words or barcode number, but not who you are. These providers handle information only to provide their service to us, under their own terms and privacy policies.
Us. The person who runs FitnessFeed can technically access information stored on our servers. We only look at it to fix a problem, to review a safety report, or to meet a legal duty.
Legal and safety. We may share information if the law requires it, or if we believe it is needed to prevent serious harm to someone.
What we do and don't do with your information
We use your information to:
- run the app and show friends what you chose to share
- send account emails, such as password resets
- keep the service safe, and review and act on reports
- find and fix problems
We don't:
- sell your information
- use your health data for advertising or marketing
- share your health data with advertisers, data brokers, or insurers
- track you across other companies' apps or websites
FitnessFeed has no ads and no third-party analytics or advertising tools today.
If this changes. If we ever add ads, analytics, or paid features, we will update this page and tell you in the app before the change takes effect. Health data from Apple Health will never be used for advertising. If we offer paid features, Apple would handle the payment, and we would only learn whether your subscription is active.
How long we keep information, and your choices
We keep your information while your account exists. You can control it at any time:
- Change what you share. Open Me, then Sharing, and change any level. Lowering a level removes the old value from what friends can see.
- Delete individual things. You can delete your own posts, comments, and photos, and stop sharing a photo without deleting it.
- Block or report. Block anyone from their profile, post, or comment, and report anything that breaks the rules.
- Delete your account. Open Me, then Privacy & safety, then Delete account. This permanently removes your profile, friends, posts, comments, reactions, photos, challenge scores, goals, sharing settings, and notifications from our servers. Any backups age out on our provider's normal schedule.
- What stays. Your data in Apple Health stays in Apple Health, which is yours. Safety reports may be kept in a form that is no longer linked to your account. Information saved on your phone is removed when you delete your account in the app or uninstall it.
- Ask us. To get a copy of your information, or to correct it, email privacy@fitnessfeed.net. We will reply within 30 days.
Depending on where you live, such as California or the European Union and United Kingdom, you may have legal rights to access, correct, delete, or receive a copy of your information. Email us and we will honor them.
Safety: reports and blocking
Because people share photos and comments, we give you tools to report and block, and we review reports.
- Reporting. You can report a post, comment, photo, or person. The person you report is not told it was you.
- When we look at content. We look at reported content to decide what to do. We may remove content or accounts that break our rules, and we may keep a record of the report.
- Blocking. A block ends the friendship and hides each of you from the other, across the whole app. The blocked person is not told.
- Serious risk. If we believe someone may be in danger, we may share the information needed to help, as described under "Who can see what."
Security, age, and changes
Security. Information is sent over encrypted connections. Our database enforces the sharing rules itself, so a friend's app can't read what you haven't shared, and photos sit in private storage. No system is perfectly secure. If a breach affects you, we will tell you as the law requires.
Age. FitnessFeed is for people 18 and older. When you create an account, we ask for your date of birth to check your age. The check happens on your phone and we don't keep your date of birth; we only record that you confirmed you are 18 or older. We don't knowingly collect information from anyone under 18, and if we learn we have, we will delete it.
Changes. If we make a significant change to this policy, we will tell you in the app before it takes effect. The date below shows when it was last updated.
Effective date: October 14, 2026
