Privacy Policy

Kiwi Labs LLC — Updated September 8, 2026

This policy covers the TRAK iOS app and trakfit.app, built by Kiwi Labs LLC (“we”). Short version: we collect what the product needs to work, we don’t sell it, and there are no ads.

What we collect

Account information. Your email address and authentication identifiers when you create an account.

Fitness data you log. Workouts, sets, reps, loads, runs, food, and body metrics you enter in the app. This is the product — TRAK stores it in order to analyze it.

Apple Health data (optional). With your permission, TRAK reads workout and activity data from HealthKit to complete your training picture. You control this in iOS Settings and can revoke access at any time.

Photos you submit. Equipment and food photos you take in the app are used to generate the result you asked for — identifying an exercise swap or logging a meal.

Chat messages. Conversations with Ask TRAK are stored on our servers and linked to your account so your history is available across sessions.

Purchases. Apple processes all payments. We receive your subscription status, never your payment details.

Website. If you join the waitlist, we collect the email address you submit and use it for a launch announcement.

How we use your data

To run TRAK: sync your data, generate training and recovery analysis, answer your questions, and manage your subscription. We do not sell your data. We also measure which ads bring people to TRAK, as described below.

Advertising measurement

We use Meta and RevenueCat to measure installs, app interactions and subscription events associated with TRAK ads. This can include app and device identifiers and purchase status. Access to the advertising identifier requires your permission through Apple’s tracking prompt. You can change that permission in iOS Settings. HealthKit data is not used for advertising measurement.

AI processing

TRAK sends AI requests through OpenRouter to Anthropic’s Claude or Google’s Gemini, depending on the feature. Claude generates programs, chat answers, workout voice edits, file imports and body scan analysis. Gemini analyzes food and equipment photos and descriptions, and generates AI workouts, coaching notes and insights.

After you acknowledge the relevant in-app disclosure, the data needed for that AI feature — which can include your profile, goals, body metrics, injuries, logged training, nutrition, recovery, messages or photos — is sent through our servers and OpenRouter to the AI provider. You can decline the disclosure and continue using features that do not require that AI processing. Material changes to the disclosed recipients require a new acknowledgment.

Voice input

Voice features (logging a meal, editing a workout by voice) use your microphone only while you hold the button. Speech is converted to text on your device where supported; otherwise Apple’s speech service processes the audio. Only the resulting text — together with the workout context needed to understand it — is sent to our servers and through OpenRouter to Anthropic (workout edits) or Google (food logging) to work out your request; the audio itself is never sent to TRAK, OpenRouter or those AI providers, and transcripts are not stored on our servers. When you correct a misheard exercise name, we save that correction to your account so it resolves right next time; corrections are deleted with your account.

Apple Health

HealthKit data is used only to provide TRAK’s features. It is never used for advertising or marketing, never sold, and never shared with third parties except as needed to deliver the service you requested.

Service providers

We use Supabase (database and authentication), OpenRouter (AI request routing), Anthropic and Google (AI processing), Apple (payments, HealthKit and speech recognition), RevenueCat (subscription status and attribution), Meta (advertising measurement), Crisp (support chat), and Resend (email). Each processes data only as needed to provide their service to us.

Retention and deletion

We keep your data while your account is active. Deleting your account in the app (Settings → Account → Delete Account) permanently removes your account, logged data, and chat history. You can also email contact@trakfit.app to request deletion or a copy of your data. Waitlist emails are used for a single launch announcement and deleted on request.

Children

TRAK is not directed at children under 13, and we do not knowingly collect their data.

Changes

We’ll post updates to this page and flag material changes in the app.
