Privacy Policy
Effective date: 9 October 2026
Last updated: 14 October 2026
This policy explains what personal data Terry: Llama Pet Step Counter ("Terry", "the app") collects, why, who handles it, how long we keep it and how you can delete it. It also covers the Terry invite page at walkwithterry.web.app.
Terry is made by Dynomite ("we", "us", "our"). Dynomite is responsible for your personal data under this policy. You can reach us at dynomite.app@gmail.com.
Please read this policy together with our Terms of Use.
On this page
The short version
- Terry reads your steps, walking and running distance and exercise minutes from Apple Health. It never writes to Apple Health.
- Your step history, distance and exercise minutes stay on your iPhone.
- Only once you add a friend (send a friend request or accept one) do we put today's step count, your daily goal and Terry's shape on our servers. Your accepted friends can see them. People you send a friend request to see only your name, username and Terry's shape. Sharing your steps stays on until you turn it off.
- We never sell your data. We never use health data for advertising. Terry has no ads and no ad tracking.
- Analytics use a random ID, not your name, email or username, and you can turn them off in Settings.
- You can export your data and delete your account in the app at any time.
1. What we collect and why
Your account
When you sign up with Apple, Google or an email and password, our sign-in provider (Google Firebase Authentication) creates an account for you.
- Account ID. A random ID that identifies your account in our systems.
- Email address. From Apple, Google or what you type. If you use Apple's "Hide My Email", we get the relay address. We use it to sign you in, to send password reset emails and to reply to you. We also save a copy in your profile.
- Name from Apple or Google. If Apple or Google shares your name (and, for Google, a profile photo link), it is kept in your sign-in record. Terry does not use it in the app.
- Password. If you sign up with email, Firebase stores your password in hashed form. We never see it.
Your profile
You give us this information during setup and in Settings. It is saved to your account so Terry can suggest a step goal, remind you to walk and restore your settings on a new device.
- Nickname, display name and username
- Birthday, height, weight and unit system (metric or imperial)
- Activity level, goals you picked during setup, and your preferred walking time
- How you heard about Terry
- Daily step goal, reminder time and rest days
- Your Friends sharing settings, and the time you chose to share with friends (when you first sent or accepted a friend request, or chose "Start sharing again"). If you stop sharing, we delete that time.
Other Terry users can't see your profile, except your display name and username, which appear on your friend card if you use Friends. Your height, weight and birthday are never shown to friends. We access your profile only when needed to run, secure or support Terry, or when the law requires.
Your username
Your username is how friends find you. Anyone, including people without the app, can check whether a username exists and see the random account ID it belongs to, which gives no access to your account by itself. To stop new friend requests, turn off "Let people find me by @username" in "What friends see" (see "Friends sharing" in section 7). Your username is part of your invite link (walkwithterry.web.app/u/yourname), so anyone you send that link to can see it.
Apple Health data
With your permission, Terry reads these from Apple Health:
- Step count
- Walking and running distance
- Exercise minutes
Terry uses them to show your progress, to change Terry's shape, to run your Live Activity and to count streaks and personal records. While your Live Activity or step sharing with friends is on, Terry checks for new steps in the background at most about once an hour.
Terry only reads. It never writes anything to Apple Health.
What stays on your iPhone: your step history, distance, exercise minutes, personal records and streaks.
What can leave your iPhone (only once you add a friend, see "Friends" below):
- Today's step count
- Your daily step goal
- Terry's shape, one of five levels (Very round, Round, Balanced, Active, Fit) worked out from your recent average daily steps
See section 3 for our health data promises.
Friends
Friends is optional. Nothing is shared until you send a friend request or accept one: adding a friend is your choice to share with them. Terry tells you what friends see right where you send or accept a request, and the "What friends see" screen lists it in full. Sharing today's steps is on from then until you turn it off, and you can stop sharing with friends completely at any time (section 7).
When you use Friends we store:
- Your friend card: display name, username and Terry's shape. Your accepted friends and anyone you send a friend request to can see it.
- Today's status: today's date, when your day ends, today's step count, your daily goal, your display name, username and Terry's shape. Only your accepted friends can see it. Your step count is left out while "Share my steps" is off. Your daily goal stays on your status even when step sharing is off. We overwrite your status each time it updates and keep no history of it. After midnight in your time zone, your friends' apps stop showing that day's steps.
- Friend requests and friendships: who sent a request to whom, the username it was sent to, and when.
- Cheers and nudges: who sent it, to whom, the kind, a short message (up to 100 characters) and when. The person you send it to sees the message in a notification. We keep a copy of each cheer for about 30 days to deal with abuse.
- Blocks: who you blocked and when. Only you can see your blocks.
- Reports: if you report someone, we store your account ID, their account ID, their name and username, the reason you chose, where you reported from (their profile or a request) and when. Reporting someone also blocks them. Our moderators review these report details, and the cheers and nudges between the two of you from the last 30 days, in the Firebase console. A short notification with their username and the reason is sent to our moderators' devices.
We check names, usernames and cheer messages against a list of blocked words, both in the app and on our servers.
Notes and photos
You can add a note to a day: text (up to 500 characters), how the walk felt and up to 4 photos. Other users, including your friends, can never see your notes and photos. We access them only when needed to run, secure or support Terry, or when the law requires.
You pick photos with Apple's photo picker, so Terry never gets access to your whole photo library. Before upload, Terry makes a new copy of the photo that leaves out location and other hidden details (metadata). Our servers then make smaller versions and remove any remaining metadata.
Notifications
- Walk reminders and Live Activity alerts are scheduled on your iPhone. Only your reminder time is saved to your account. The one exception is the Live Activity that our server starts at your walk time when you haven't opened Terry for a day or more (see "Live Activities").
- Friends notifications (friend requests, accepted requests, cheers and nudges) are sent through Google Firebase Cloud Messaging and Apple Push Notification service. If you are signed in and allow notifications, we store a push token, a random ID for your install, your account ID, your platform and when it was last updated. Each notification includes the sender's display name or username, any cheer message, and the sender's account ID so Terry can open their card. We also keep a short record of notifications sent between two people, for about 2 days, to limit how many can be sent.
Live Activities
Your Live Activity (today's steps, goal, streak and countdown) is built on your iPhone. It shows on your Lock Screen and in the Dynamic Island, where anyone holding your phone can see it. The "Terry only" style shows Terry's mood and a progress bar instead of numbers.
So Terry can still join you at walk time when you haven't opened it for a while, while Live Activity and your walk reminder are on, your iPhone sends our server (Google Firebase) the times of your next walk cards, for up to 7 days after you last opened Terry, and what each card starts with: your daily goal, the Lock Screen style, Terry's greeting and the countdown to midnight. It never sends your steps or your streak; the card shows 0 steps until Terry updates it on your iPhone. If you reach your goal before walk time, your iPhone takes that day's card off the list, so our server can tell that you reached your goal that day. It also sends your account ID, Live Activity and Firebase push tokens and a random ID for your install, so Apple can start the card at walk time and end it at midnight even when Terry is closed. Turning Live Activity, the walk reminder or notifications off, signing out or deleting your account deletes them; otherwise they are deleted 30 days after you last opened Terry. Only the iPhone you used last gets these cards.
Purchases (Terry+)
Apple handles all payments. We never see your card or payment details.
We use RevenueCat to check whether you have Terry+. RevenueCat receives your purchase and renewal records from Apple, your account ID (after you sign in; a random ID before that) and your random analytics ID (see below), so we can understand which plans people buy.
As with any internet connection, Google (Firebase) and RevenueCat also receive your IP address and basic device and app details when Terry connects to them.
Analytics and crash reports
We use PostHog to understand how Terry is used and to find bugs. Analytics use a random ID instead of your name, email, username or account ID, and the app never sends those to PostHog. Because RevenueCat stores that random ID with your account ID for purchase records (see Purchases), analytics are pseudonymous, not fully anonymous.
PostHog receives:
- App events from a fixed list (for example, which setup step you finished or which plan you viewed), with a fixed set of details such as how you heard about Terry, your unit system, plan, price and currency, and error codes.
- The screens you open, and when the app is installed, updated, opened or closed.
- A random ID created by the PostHog software (not your Apple advertising ID).
- Device model, iOS version, app version, language, time zone, screen size and whether you use Wi-Fi or mobile data.
- Crash and error reports, which can include error text from Apple, Google or RevenueCat software.
- Your device's IP address reaches PostHog when the app connects to it. PostHog drops it instead of storing it with your events.
We never send health data, notes, photos, messages or your profile details to analytics. The only text you write that reaches PostHog is feedback you choose to send (see Feedback form). Terry also asks PostHog which features are switched on (for example, whether Friends is available), using the same random ID.
Your analytics ID is shared with RevenueCat (see Purchases), even when "Share usage data" is off. RevenueCat sends purchase events, such as plan, price, trials and renewals, to PostHog under your analytics ID, and these events can include RevenueCat's customer ID, which is your account ID.
Turn it off: Settings > Privacy > Data & privacy > "Share usage data" (in version 1.0.0, Settings > Privacy > "Share usage data"). This stops analytics, crash reports and feature exposure events from the app. Terry still downloads feature switches from PostHog, which sends your random ID and IP address but no usage events. It does not stop the purchase records Apple and RevenueCat keep, or the purchase events RevenueCat sends. Signing out gives you a new random analytics ID.
Device checks
Terry uses Firebase App Check with Apple's App Attest and DeviceCheck to prove that requests come from the real app. This sends a device check to Apple and Google. It does not include your personal details.
Feedback form
If you send feedback in Terry, the reasons you picked, your message (up to 1,000 characters) and the time go to PostHog as a survey response under your random analytics ID, not your account ID. If "Share usage data" is off, Terry opens an email to us instead (see Emails to us). Version 1.0.0 stored feedback in our database without your account ID. Please do not put personal details in your message.
Emails to us
If you email us, we receive your email address and whatever you write. We use it to reply and to improve Terry.
Invite page
The invite page at walkwithterry.web.app has no cookies, no analytics and no tracking. It reads the username from the link in your browser. It is hosted on Firebase Hosting (Google), which processes your IP address and browser details to deliver the page. The page tells your browser not to send its address to other sites.
2. What we do not collect
- Your precise location. PostHog may estimate your country and city from your IP address.
- Your contacts
- Your camera or microphone
- Your Apple advertising ID. Terry does not track you across other companies' apps and websites.
- Session recordings of your screen
- Your payment details
Terry has no advertising software.
3. Our promises about Apple Health data
- We never sell health data.
- We never use health data for advertising, marketing or data mining.
- We never share health data with third parties, except (a) the people you choose in Friends: your accepted friends see today's steps, your goal and Terry's shape, and people you send a friend request to see Terry's shape; and (b) Google Firebase, which stores those values only on our behalf so Terry can show them to your friends. Health data is never sent to our analytics or purchase providers.
- Terry does not save health data to iCloud or iCloud Drive. Like all app data, the copies on your iPhone are part of your own encrypted device backup if you turn device backups on.
- Terry never writes to Apple Health.
- You can stop Terry reading Apple Health at any time in the Health app or in iPhone Settings > Privacy & Security > Health > Terry. To stop sharing with friends, see "Friends sharing" in section 7.

- To protect people and Terry: to enforce our Terms, to investigate abuse, fraud or security problems, or to protect the rights, safety or property of our users, the public or Dynomite.
- If Dynomite is sold or reorganized. Your data may move to the new owner, who must keep following this policy for it.
- With your permission.
We do not sell your personal data, and we do not share it for cross-context behavioral advertising.
5. Where your data is stored
Our servers are in the United States. If you live elsewhere, your data is sent to and stored in the United States, where data protection laws may differ from yours. Where the law requires it, we rely on our providers' standard data protection terms for these transfers.
6. How long we keep it
| Data | How long |
|---|---|
| Account, profile, username, notes, photos, friends, requests, your blocks, reports you filed, push tokens | Until you delete them or delete your account |
| Your friend card and today's friends status | Replaced at each update, deleted when you stop sharing with friends or delete your account |
| Cheer copies | About 30 days, even if you delete your account |
| Notification limit records | About 2 days |
| Live Activity walk times, card settings and push tokens | Until you turn Live Activity, the walk reminder or notifications off, sign out or delete your account; otherwise 30 days after you last opened Terry |
| Reports other people filed about you | As long as we need them for safety, moderation and to stop banned users coming back. They have no fixed end date and are kept after you delete your account. |
| A block someone else made of you | Stays in their account (it holds only your account ID) after you delete yours |
| Feedback form messages | Sent from version 1.0.1 on: as long as PostHog keeps them, like analytics. Sent from version 1.0.0: no fixed end date; they are not linked to your account, so we cannot find them to delete. |
| Analytics and crash reports | As long as PostHog keeps them under its settings and policy. They are kept under a random ID, which RevenueCat can connect to your account. |
| Purchase records | Kept by Apple and RevenueCat under their own policies, including after you delete your account |
| Emails to us | As long as needed to help you and keep a record |
| Server backups | Our providers may keep backup copies for a limited time under their own retention schedules |
We may also keep data longer when the law requires it or to resolve disputes and enforce our Terms.
7. Your choices
- See and export your data: Settings > Privacy > Data & privacy > "Export your data". You get a file with your profile, sharing settings, note text, rest days, friends and friend requests. Photo files are not included.
- Delete your account: Settings > My Account > "Delete account". Terry deletes your notes and photos, your friends data, requests, cheers, your blocks, reports you filed, push tokens, profile, friend card, status and username, then deletes your sign-in account. If you signed in with Apple, we also ask Apple to revoke Terry's access to your Apple ID. Deletion cannot be undone. Deleting your account does not cancel Terry+; cancel that in your Apple settings. If you cannot sign in, email dynomite.app@gmail.com from the address on your account and we will delete it for you.
- Data on your iPhone: Terry keeps some data on your iPhone so it works offline (for example a copy of your profile, notes, friends' statuses, photo previews, personal records and settings). Signing out or deleting your account does not remove every local copy. Deleting the app removes all of it.
- Friends sharing: open "What friends see" (in Friends, tap the sharing line on your own card, or go to Settings > Privacy > Friends visibility). Turning off "Share my steps" stops sharing your step count; your goal, name, username and Terry's shape stay visible to your friends. Turning off "Let people find me by @username" stops new friend requests. To stop sharing completely, tap "Stop sharing with friends" at the bottom of that screen: Terry deletes your friend card, today's status and the friend requests you sent from our servers, so friends and the people you sent a request to no longer see your name, Terry, steps or goal, and Terry stops updating them. Your friends stay on your list, you still see the friends who share with you, and the requests you received and your blocks stay. "Start sharing again" on the same screen, or sending or accepting a friend request, starts sharing again. A friend who stopped sharing can still see what you share; Terry lists them under "Stopped sharing" in Friends, where you can remove or block them. You can also remove or block anyone at any time.
- Analytics: Settings > Privacy > "Share usage data".
- Apple Health: change access in the Health app or iPhone Settings.
- Notifications: change them in iPhone Settings > Notifications > Terry.
- Live Activity: pick the "Terry only" style or turn it off. Turning it off also deletes your Live Activity walk times and push tokens from our server.
8. Your rights where you live
Depending on where you live, you may have the right to:
- access the personal data we hold about you and get a copy
- correct it
- delete it
- object to or restrict how we use it
- move it to another service
- withdraw consent you gave, at any time (this does not affect what we did before)
- complain to your local data protection authority
Most of this you can do yourself in the app (section 7). For anything else, email dynomite.app@gmail.com. We may need to confirm your identity before we act, and we may refuse requests the law allows us to refuse. We will not treat you differently for using your rights.
EEA, UK and Switzerland. We use your data:
- to provide Terry under our Terms (account, profile, Friends, notes, purchases)
- with your consent (reading Apple Health, sharing with friends, notifications); you can withdraw it as described above
- for our legitimate interests in keeping Terry safe, fixing bugs and improving the app (analytics, crash reports, device checks, abuse reports), which you can object to
- to meet legal obligations
California and other US states. We do not sell or share personal information as those laws define it, and we do not use sensitive personal information for anything beyond providing Terry. The categories we collect are listed in section 1.
Nothing in this policy limits rights you have under the laws where you live that cannot be limited by agreement.
9. Security
We use our providers' security features, including encrypted connections, access rules that limit who can read each record, and device checks. No system is completely secure, and we cannot guarantee the security of your data. You are responsible for keeping your device and password safe. To the extent the law requires, we will tell you about a data breach that affects you.
10. Children
Terry is not directed to children under 13, or under 16 in the European Economic Area and the United Kingdom. If we learn that a user is under these ages, we will delete their account. If you believe a child has given us personal data, email dynomite.app@gmail.com and we will delete it.
11. Changes to this policy
We may update this policy from time to time. We will post the new version with a new "Last updated" date. If a change is significant, we will tell you in the app or by other reasonable means. If you keep using Terry after a change takes effect, the updated policy applies. Where the law requires your consent to a change, we will ask for it.
