Hejje

Hejje is a privacy-first fitness and training tracker for people who want to log their workouts without handing their personal data over to a cloud service. It tracks runs, walks, hikes, rides, strength training, food, water and weight while keeping your data encrypted on your phone before it syncs.

The app works offline, requires no email or password, and avoids ads, analytics and tracking SDKs. Your fitness history stays under your control, with an on-device assistant that can answer questions about your own training and nutrition history without sending that information to the cloud.

On-Device Fitness Assistant

Ask questions about your own training history without sending your data to a cloud service. The assistant works with the information stored on your device, making it possible to explore your activity and progress while maintaining the app's privacy model.

Encrypted Data and Recovery

Privacy is built into how Hejje stores and syncs information.

Your data is sealed on the device first, while the server only stores ciphertext that it cannot read. There is no email address, phone number or password required during setup.

When you create your account, you receive a recovery key. This key is the way to regain access to your encrypted vault when moving to a new device, so keeping it safe is essential.

Offline-First Usage

Hejje is designed to remain useful without a constant internet connection.

You can record and review your training with the radio turned off, while encrypted synchronization happens when connectivity is available. This makes the app suitable for workouts where connectivity is limited or intentionally disabled.

Widgets, Media and Sharing

Small features make everyday tracking easier without compromising the privacy-focused approach.

• Home screen widgets
• Photos and videos attached to activities
• Metric or imperial units
• Light and dark modes
• Selective sharing so you decide which sessions to share

Built For Privacy-Conscious Training

Hejje is designed for people who want a complete personal training log without giving up control of their fitness data. Instead of treating workout history, routes, nutrition and weight as cloud-first data, the app keeps information encrypted on the device before synchronization.

It is suited to runners, cyclists, hikers, gym users and people who want training, nutrition and weight tracking in one private workspace.

Common Use Cases

Running and outdoor training: Record routes, pace, distance, climb and heart rate while keeping activity data encrypted.

Strength training: Log exercises, sets, reps and weight while following estimated 1RM progress.

Nutrition tracking: Monitor food, calories, protein, water and weight alongside your training history.

Offline workouts: Continue tracking when connectivity is unavailable or intentionally switched off.

Personal progress tracking: Use streaks, calendars, weekly totals, personal bests and charts to understand your consistency.

Private fitness analysis: Ask the on-device assistant about your own history without sending your fitness data to a cloud service.

Cross-device training: Keep encrypted training data synchronized between iPhone and Android.

Why It Matters

Most fitness trackers make it easy to collect personal information, but Hejje takes a different approach by making privacy part of the product's foundation. There are no ads, analytics or tracking SDKs, no email or password required, and your server-side data remains encrypted in a form the server cannot read.

That makes Hejje a practical choice for anyone who wants detailed training and nutrition tracking while keeping their personal fitness history under their own control.
