TusslingsTusslings Consumer Health Data Privacy Policy
Last updated: 28 October 2026
This policy is provided by Butterknife LLC, doing business as Tusslings ("we"). It supplements the Tusslings Privacy Policy and explains how the Tusslings apps handle consumer health data: personal information that is linked or reasonably linkable to you and identifies your past, present or future physical or mental health status. It applies to residents of Washington, Nevada and Connecticut, and we extend the same treatment to everyone.
1. The short version
- Tusslings has no server and no accounts. Your consumer health data is collected and processed on your own watch and phone. Butterknife LLC never receives it.
- We never sell consumer health data and never share it with third parties for any purpose.
- The apps move some data between your own devices and to places you choose, such as Garmin Connect, Health Connect, your Garmin Edge, or another player's watch. Section 5 lists each one.
2. Consumer health data the apps handle
| Category | Specific data | Where it comes from |
|---|---|---|
| Activity | Steps or wheelchair pushes, daily goal, floors, distance, calories, intensity minutes, seven days of history | Your Garmin watch; Apple Health or Health Connect if you allow it |
| Heart and body signals | Heart rate, resting heart rate, heart-rate zones, stress, Body Battery | Your Garmin watch; Apple Health or Health Connect |
| Sleep | Bedtime and wake time from your Garmin profile; sleep from Apple Health or Health Connect; sleep hours you log | Your watch, health platform, or you |
| Workouts | Sport, times, distance, pace, heart rate, speed, calories, steps, power, cadence, laps, sets, reps, lifted weights, effort and feel ratings; GPS location during recorded outdoor workouts | Your watch's recordings; workouts imported from Apple Health or Health Connect; activity FIT files you import; manual entries and guided phone sessions. Phone sessions record timer duration and user-marked steps, not GPS or health sensors. |
| Phone coaching | Training goal, preferred days, equipment, experience and available time; energy, soreness and pain/feeling-unwell check-ins; activity notes | You |
| Body measurements and goals | Sex, age, height, weight, activity level, and whether your goal is to lose, maintain or gain weight | You, in the nutrition feature |
| Stroller profiles | Runner weight, stroller model, stroller weight, aggregate passenger and gear weights or measured total load, surface, export preference | You, in stroller setup on the phone or watch; no child names, ages or individual passenger records |
| Stroller calibration and estimates | Up to three paired solo/stroller trial summaries and one pending solo trial: recording identifiers and times, mean/range of heart rate and speed, profile conditions; personal pace estimate and coverage, separate from actual activity measurements | Trials you record and choose to calibrate on the watch; profile and calibration snapshots in recovery and activity history |
| Nutrition | Foods you eat, portions, calories and macronutrients; meal quality you log | You |
| Inferences | Your tussling's mood from heart rate, stress, Body Battery and bedtime; calorie and macronutrient targets; whether you use a wheelchair, inferred from your Garmin push goal; workout achievements; local general-fitness suggestions using your preferences, check-ins, plan and effort feedback | Calculated by the apps on your device |
| Device data that could be linked to health data | A code derived from your Garmin device ID, random installation identifiers, watch model | Your devices |
Wellbeing inferences are game effects. A "tired" or "frazzled" tussling is not a diagnosis, and Tusslings does not identify medical conditions. Phone coaching uses local rules, not a generative AI service or a medical recovery assessment. No coaching context is sent to a server.
3. Why the apps process it
Only to provide the features you use:
- Hatching eggs and growing your tussling from your activity
- Setting your tussling's mood and condition
- Coaching, recording and summarising your workouts and recognising achievements
- Suggesting a session or rest from your training preferences, daily check-in, existing plan and recent effort ratings, and keeping your activity journal
- Configuring stroller activities and calculating the personal pace estimate you choose to calibrate
- Calculating nutrition targets and showing your food diary
- Showing your Health trends, history and progress
- Battles, gifts and trades with other players, and live data on your Edge
We do not use consumer health data for advertising, marketing, unrelated profiling, research, training shared models, or any purpose not listed here. Optional personal stroller calibration happens on your own devices.
4. Consent
The apps do not read consumer health data until you agree:
- Phone health data is read only after you grant access in Apple Health or Health Connect, and only the types you grant.
- Garmin watch data is read only after you install the Tusslings watch apps and accept the permissions shown at installation.
- Nutrition data exists only if you enter it, after an in-app notice you must acknowledge before targets are shown.
- Training preferences, check-ins, manual activities and reflections exist only if you enter and save them. A phone session begins when you start one; activity summaries enter the journal when you import them or sync a saved guided-workout result from your watch.
- Stroller profile values exist only if you enter them. Save and sync profile sends the entered weights and settings to your selected Garmin watch; calibration uses trials you choose to record. Recording weight export is off unless you enable it. No new health permission is added.
- Each transfer in section 5 that goes beyond your own devices happens only when you turn that feature on or start that action.
You can withdraw consent at any time (section 7).
5. Where consumer health data goes
We do not sell or share consumer health data with third parties. The apps send data only as follows, each at your request:
| Destination | What | How |
|---|---|---|
| Your own phone and watch | Daily activity, intensity minutes, logged meals and sleep, workout results; Wear OS workout recordings including heart rate and GPS route | Through the Garmin Connect app or Garmin's connection software, or Google Play services for Wear OS |
| Your selected Garmin watch and phone | Stroller profile weights and settings on Save and sync profile; profile and calibration progress on readback. Private profile sync includes weights regardless of recording export preference | Existing Garmin connection |
| Your paired Wear OS watch and phone | Stroller recording profiles, calibration and estimate metadata. Weights and calibration/estimate metadata are omitted from recording transfers and game snapshots unless Export profile weights is enabled | Google Play services Data Layer |
| Your Garmin Connect account | Activities you record, with Tusslings' workout fields | Garmin syncs your watch's activities under Garmin's policy |
| Your Garmin Connect account, stroller activities | Estimated pace, coverage and calibration status as separate fields; total pushed weight only when Export load to Connect is enabled. Never runner weight or separate stroller/passenger/gear weights in these activity fields | Garmin activity sync |
| Health Connect (Android) | Workouts you choose to export, including heart rate and, with separate permission, the route | Android; other apps you authorise may read it |
| Your Garmin Edge | Live workout data including heart rate and Training Effect | Unencrypted short-range ANT radio |
| Another player's watch | No consumer health data. Battles and gifts send your tussling, its nickname and a device-derived code only | Short-range ANT radio |
| A destination you choose for a training export | Training preferences, check-ins, journal/reflections, current session, saved workouts and plans | Only when you copy the prepared export to the clipboard or use the system share sheet |
| Backups and profile transfers you request | App-state backups or profile transfers can include stroller settings and calibration; creature-only backup codes do not include the stroller profile | Your chosen backup or transfer path; later export-preference changes do not delete existing copies |
Garmin, Apple and Google operate the services that connect your devices. They are not our processors; they act under their own terms with you.
Butterknife LLC has no affiliates that receive consumer health data, and the list of third parties with whom we share it is empty.
6. How long it is kept
| Data | Kept |
|---|---|
| Food diary | 400 days |
| Logbook (meals, sleep) | 180 days |
| Completed workout plans | 730 days |
| Nutrition profile, game data, workout summaries on the watch | Until you delete it or uninstall |
| Workout recordings and imported workouts (Android, Wear OS) | Until you clear the app's data or uninstall |
| Phone activity journal and imported summaries | Until you remove them or delete app data; up to 3,000 entries, without automatic eviction |
| Phone daily check-ins | Check-ins older than 365 days removed when you save a new check-in |
| Training preferences and unfinished phone session | Until changed, saved/discarded or app data deleted |
| Stroller profile and phone draft | Until replaced, cleared or removed with app data; Settings → Clear companion records removes the phone draft |
| Stroller calibration | Current calibration is bounded to three pairs and one pending solo trial; reset or a runner/stroller/load/surface change clears it. Recovery and saved activities retain their own snapshots until those records are removed |
| Mood readings (heart rate, stress, Body Battery) | Not stored |
7. Your rights
You have the right to:
- Confirm and access. Know whether consumer health data about you is collected, shared or sold, and access it. All of it is on your own devices and visible in the apps; we hold none. Settings also lets you prepare a local training export and choose whether to copy or share it.
- Know who receives it. See section 5. We share with no third parties or affiliates.
- Withdraw consent. Turn off health access in Apple Health, Health Connect, Wear OS settings or on your Garmin watch; stop using optional features; or uninstall.
- Delete it. Use Settings → Clear companion records for the listed local records. Remove saved routes, relay plans and race recovery backups in Routes & courses. Clear the app's data in your phone's settings, or uninstall the apps, to remove other app stores. Copies you placed elsewhere (Garmin Connect, Health Connect, backups) are deleted there.
- Appeal. If we decline a request, you may appeal by replying to our decision.
To exercise any right, or to ask us to confirm in writing that we hold no consumer health data about you, email info@butterknifellc.com with "Consumer health data request" in the subject. We respond within 45 days, extendable once by 45 days when reasonably necessary, and we will tell you why. We do not charge for requests and will not treat you differently for making one. Because we hold no data, we will not ask you for more information than we need to reply.
Appeals. If we deny a request, email the same address with "Appeal" in the subject within 45 days. We will answer within 45 days. If you are unhappy with the result, you may contact the Washington State Attorney General (atg.wa.gov), the Nevada Attorney General (ag.nv.gov) or the Connecticut Attorney General (portal.ct.gov/ag).
8. Geofencing
Tusslings does not use location to set up a virtual boundary around any health care facility, or for any purpose other than the location features described in the Privacy Policy.
9. Changes
If we change how Tusslings handles consumer health data, we will update this policy and its date. We will ask for your consent before collecting new categories of consumer health data, using it for a new purpose, or sharing it with anyone.
