The deal,
in plain words

Last updated 26 August 2026

This is the agreement between you and FitLexx. Using the app means you accept it. It is written to be read rather than skipped, so it is short and there is nothing buried in it.

1. What FitLexx is

FitLexx builds a training and nutrition plan from what you tell it about yourself, and rebuilds it as you go using what you actually did. It logs your sessions, tracks your day, and can explain in words why anything changed.

The numbers in your plan come from a solver we wrote — a piece of software with rules in it, not a guess. Where an AI model is involved it chooses between options the solver has already approved and puts them into sentences. It does not invent your weights.

2. What FitLexx is not

Exercise carries risk. Lifting weights carries more. You are responsible for deciding whether a session is safe for you on the day, and for stopping when something hurts.

Talk to a doctor before starting, and especially if you are pregnant, recovering from an injury or surgery, taking medication, or living with a heart, joint, metabolic or eating-related condition. If something feels wrong while you are training — chest pain, dizziness, faintness, a sharp pain in a joint — stop and get medical help. Do not wait to finish the set.

Nutrition targets are general and calculated from what you entered. They take no account of an allergy, an intolerance, a medication or a condition you have not told the app about, and they are not a clinical diet.

3. Who can use it

Anyone 18 or over who can enter into a contract. FitLexx is not for children, and we do not knowingly create accounts for them.

4. Your account

One account per person. Signing in is a Google account or a link sent to your email address, so keeping that mailbox secure is what keeps your account secure.

Anything done through your account is treated as done by you. Tell us at support@fitlexx.com if you think somebody else has got in.

5. What it costs

Paid plans are planned and are described on the home page as what they will contain. Until they are actually built and switched on, they are a statement of intent and not something you can buy. When that changes, the price, what is included and how to cancel will be set out here first, and you will be asked to agree before anything is charged. Nothing will be charged to anybody who does not choose to pay.

6. Refunds

There is nothing to refund at the moment, because nothing is charged. When paid plans start, this section will say exactly when a refund applies and how to ask for one, and it will be published before the first payment is taken rather than after.

If you are ever charged in error, write to support@fitlexx.com and we will return it.

7. Using it fairly

Do not:

• use another person’s account, or let somebody else use yours;
• try to reach data that is not yours, or probe the service for ways to;
• scrape it, resell it, or wrap it in something else and sell that;
• use the coach to generate abuse, or anything unlawful;
• put load on it that is not a person using an app.

Security research is welcome. If you find something, tell us at support@fitlexx.com before you tell anyone else, and do not take other people’s data while you are proving it.

8. Your data stays yours

What you log belongs to you. We store it to run the service and for nothing else — the privacy page lists every row of it, where it lives, and the two buttons that get it back or erase it.

We do not sell it and we do not put advertising in front of you.

The app itself — the software, the design, the name and the mark — belongs to us.

9. What we promise, and what we don’t

We will run FitLexx carefully and fix what breaks. We do not promise it will never be down, never be wrong, or never lose a feature. It is early software and it is free, and pretending otherwise would be the first dishonest line on this page.

We will tell you before removing something you rely on, and your export always works — so you are never locked in by a feature going away.

10. Ending it

You can end it at any moment from You → Your data → Delete account. It is immediate and it is final; nothing is retained for a “grace period” and nothing is recoverable afterwards. Take an export first if you want to keep your history.

We can end it if you break section 7, or if we stop running the service. If we stop running it, you get notice and time to export.

11. Liability

To the extent the law allows, FitLexx is not liable for injury, loss or damage arising from following a plan, from the service being unavailable, or from data you lost by deleting your own account. Nothing here limits liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be limited under Indian law.

Because the service is free, any liability that does apply is limited to what you have paid us, which is nothing.

12. Changes

When these terms change materially, the date at the top changes and you are told in the app before the change applies. Continuing to use FitLexx after that means you accept the new version; if you do not, delete your account and nothing further applies.

13. Law

These terms are governed by the law of India, and the courts of India have jurisdiction over any dispute. If you are a consumer, this does not take away any right you have under consumer law where you live.
