Answers to the most common questions about Maintenea. Can’t find yours? Write to mail@resetnak.cz.
What is Maintenea?
Maintenea is a web application for logging strength workouts and stretching and for tracking body progress (measurements, weight, progress photos). Everything in one clean system, without spreadsheet chaos.
Is Maintenea free?
Yes, completely. No subscriptions, no paid features, no ads. It is a personal project run for the joy of it.
Do I need to install an app?
No. Maintenea runs in the browser on desktop and mobile. As a progressive web app (PWA) you can also add it to your phone’s home screen and use it like a native app — your data stays viewable even offline.
How do I start?
Register with your e-mail, or sign in with Google; the iOS app also offers Sign in with Apple. Then log your first workout right away — the app ships with a ready-made library of exercises and stretches.
What can I track?
Strength workouts set by set (reps, weight, notes), stretching and mobility sessions, body measurements, weight, and progress photos. The dashboard shows weekly volume and trends over time.
Who can see my data and photos?
Only you. We do not sell data, show no ads, and load no analytics unless you opt in. Progress photos sit under long, unguessable addresses that the app hands only to your account. Treat such an address like a password: whoever has it can open the photo. See the Privacy Policy for details.
Where is my data stored?
The application and database run on servers in the European Union. Progress photos are stored by Cloudinary with GDPR-compliant transfer safeguards (Standard Contractual Clauses).
How do I delete my account and data?
Right in the app: Settings → Your data → Delete account. The account and all data, including photos, are deleted immediately and irreversibly; you can download everything first via Export. Alternatively, write to mail@resetnak.cz from the e-mail address your account is registered to.
Does Maintenea work offline?
Partially, yes. As a PWA it remembers your data from the last visit, so you can review workouts and progress without a connection. Logging new entries requires a connection; an unfinished workout draft is saved locally so you never lose it.
Which languages does Maintenea support?
Czech and English. The language is set automatically from your browser and can be switched in the settings at any time.
Does Maintenea replace a coach or a doctor?
No. Maintenea is a logging and overview tool — it does not replace professional medical or coaching advice. Consider consulting a professional before starting a new training programme.
How is Maintenea different from Strong or Hevy?
Strong and Hevy are established apps with many more users. Both have a free version with limits and a paid upgrade, and Hevy adds a social feed. Maintenea has no paid tier: routines, charts and your full history are free, and there is no feed. It runs in the browser and as an iPhone app on the App Store; there is no Apple Watch or Android app yet. If you need those, one of them will suit you better.
What does the workout log actually do?
Per-set reps and load; notes per exercise (per set too in the iPhone app); supersets; a rest timer that starts when you tick a set off; kg or lb; PR markers and an estimated 1RM per exercise; a suggested next load based on your last logged RIR; a plate calculator for a 20 kg / 45 lb bar. Stretching sessions log the hold time per stretch and a discomfort score before and after.
Can I bring my workouts over from Strong, Hevy or a spreadsheet?
Yes. Settings → Your data → Import reads a CSV exported from Strong or Hevy as it is, and a spreadsheet in Maintenea’s format (there is a sample file to download). Files up to 5 MB. In Strong: Settings → Export Strong Data. In Hevy: Profile → Settings → Export & Import Data → Export Data → Export Workouts. If a Strong export doesn’t say whether weights are kg or lb, the import asks. Check the preview and confirm; workouts already in the account are skipped.
Can I export my data?
Yes, any time. Settings → Your data → Export downloads everything (workouts, stretching, body metrics) as one JSON file. Workouts alone can also be downloaded as CSV. Nothing is locked in.
Is there an Android or iOS app?
For iPhone, yes: Maintenea is on the App Store at https://apps.apple.com/app/id6811350987. There is no native Android app. On Android, add the web app to your home screen: it runs full-screen and shows your data offline.
What happens to my data if the project stops?
You would get notice in the app and by e-mail well in advance, with export available the whole time. Maintenea is one person’s project, so this is a fair question; it costs little to run, and the author uses it himself.
