Fitnezze runs on the website (fitnezze.com) and the Fitnezze Android app. Both use the same account and the same data, described per category below.
Account: your Fitnezze login is a Hassle Studio account, the same account used to sign in to every Hassle Studio product. When you sign in with Google we receive your name, email address, and Google profile photo. We also record which Hassle Studio product you first signed up from.
Progress logs: body weight, body fat percentage, body measurements (chest, waist, hips, arms), and the notes you write. Notes our coaches add to your logs are stored with them.
Workouts: your workout sessions, the exercises, sets, weight, and reps you log, the custom workouts you build, the programs you start, and which program videos you have watched.
This data is private to your account. Besides you, only authorized Fitnezze staff can view it, to provide coaching and support.
In the Android app you can log what you eat. For each entry we store the food name, portion in grams, calories, protein, carbohydrate, and fat, the meal (breakfast, lunch, dinner, or snack), and the date. The website does not collect nutrition data.
The inputs for your daily meal plan (goal, body weight, and menu choices) are saved only on your device and are not sent to our servers.
Plans can only be bought on the website. The Android app sells nothing and has no in-app purchases.
Website payments are processed by our payment partner Pakasir. We do not store card or bank account details on our servers. We keep transaction records (plan, amount, status, timestamp) for accounting and support.
On the website: we use PostHog to count page views, page exits, which features are used (for example training features opened, which can include an exercise identifier), completed purchases, and server errors, and Sentry to catch errors and measure performance. When you are signed in, both are linked to your account ID and email (PostHog also receives your name). When an error happens, Sentry may record a short replay of the page with all text masked and all images and media blocked. The website also loads the Meta Pixel, which records page views to measure our marketing. Like any website, these services receive technical data such as your IP address, browser, and device.
In the Android app: the app contains no analytics, advertising, or crash reporting tools. It only connects to Supabase and Google Sign-In.
The Android app keeps your login session in encrypted storage protected by the Android Keystore. It also saves your language, whether you finished onboarding, your meal plan inputs, and exercise swaps for your sessions in the app's local storage. This data stays on your device and is removed when you uninstall the app or clear its data.
We use your data to run the features you use: logging and showing your progress, workouts, and meals, syncing them between the website and the app, delivering the plans you purchase, and letting our coaches review your logs and add notes. We also use it to process payments, fix errors, prevent abuse, and answer your support requests.
Your health, fitness, and nutrition data is used only to run these features. It is never sold and never used for advertising. Your weight, body measurements, body fat, notes, and food and nutrition entries are never sent to analytics or advertising partners.
We do not sell your data. We share limited data with service providers that help us run Fitnezze:
Supabase: database and login for the website and the app.
Google: Sign-In with your Google account.
Pakasir: payments on the website.
PostHog and Sentry: analytics and error monitoring on the website only.
Meta: page view measurement on the website only.
Upstash: rate limiting to prevent abuse, which uses your IP address.
All data is sent over encrypted (HTTPS) connections. We may disclose data if required by law.
We keep your account data while your account is active. You can request deletion at any time in the app under Profile > Delete account, or on the Delete account page (fitnezze.com/delete-account).
Because your login is a Hassle Studio account, deletion removes the account and its data across all Hassle Studio products, including Fitnezze. We process every request within 30 days. Some records (transactions, tax filings) must be kept for the period required by Indonesian law.
You can access, update, or delete your data from your account dashboard. For requests we cannot fulfil in the app, email [email protected] and we will respond within 14 days.
