Terms

Last updated 26 October 2026

These terms are the agreement between you and Reckoner. They cover who may hold an account, what the service promises and what it deliberately does not, how lifting under a program a computer wrote is your own responsibility, and how either of us ends the arrangement. Using Reckoner means accepting them.

The short version

• Reckoner tells you how much weight to lift. It is not a doctor, a physiotherapist or a coach who can see you. The judgement in the gym stays yours.
• You must be 13 or over, and the account is yours alone.
• Reckoner is open to everyone.
• It is free, it is young, and it runs on one server. Expect it to change under you and to be down sometimes.
• Your training log is yours. Export it whenever you like and delete it whenever you like. Deletion is immediate, and the backups that can still hold it for up to 30 days are never restored from.
• Tell us what is broken and you get an answer with a reason, in public on the board, where what you wrote appears in your own words.
• Nothing here takes away a right your national consumer law gives you.

Who you are agreeing with

Reckoner is operated by Inner Skill Set, registered in the Netherlands with the Kamer van Koophandel under number 75619563. These terms call it "we" and "us". The service is the website at reckoner.fit, the Garmin Connect IQ watch app, and the server behind both.

You join by creating an account at reckoner.fit. If you do not accept them, do not use it. The current version is always at https://reckoner.fit/terms.

Who can use Reckoner

You must be 13 or over. Onboarding asks your date of birth and enforces that floor at signup, and it is the same floor Garmin sets for a Connect IQ account. If you are under 13, Reckoner will not build you a program, and you are told the date you can come back.

Reckoner also holds health data about you, on the basis of your explicit consent. In some countries a person under 16 cannot give that consent alone and needs a parent or guardian to give it with them. If that is your situation, get it before you fill in your profile.

One account belongs to one person. Do not share it, and do not hand out the sign-in codes we email you or the token a paired watch holds. Anything done through your account is treated as done by you.

Access

We may withdraw access, close signups, or change how invitations work, and we will not always be able to say why in advance. Nothing has been paid for, so nothing is owed back.

If you joined as a founding member, you get your first year of Reckoner Unlocked free. That year starts on the day Reckoner Unlocked launches, not on the day you signed up. After it, the founding intro price is yours for life. It applies to any membership you hold, including one you start again after a break, it does not depend on how often you train, and it does not lapse. We will not raise it.

Lifting is your responsibility

Reckoner is not medical advice. The training loads, progressions, calorie and macro targets and strength standards it produces are approximate and evidence-informed. They are a starting point to adapt. They are not a prescription, not a diagnosis, and not physiotherapy.

Reckoner cannot see you. It does not know your technique, your injury history, what you slept, or that today's bar speed is wrong. It reads the numbers you type and adjusts arithmetic. Deciding whether a prescribed set is safe to attempt is yours alone, in the moment, every time.

Strength training carries a real risk of injury. By using Reckoner you accept that risk knowingly, and you agree that a number on a screen never overrides your own judgement, a qualified coach who is watching you, or your doctor.

Talk to a doctor before you start, and stop and get advice if something hurts, especially if you are new to lifting, coming back from a layoff or an injury, pregnant, or managing a condition that training could affect. If you feel faint, short of breath or have chest pain, stop and get medical help.

Setup asks everyone the standard health check before exercise: a short list that includes a heart condition or high blood pressure, chest pain, dizziness or fainting, a long-term condition and a doctor saying you should only exercise under supervision. You tell us whether you are fit to train. If anything on the list applies to you, we ask you to check with your healthcare professional first. Once they have cleared you to exercise and you tell us so, Reckoner starts you gently. We don't see or check that clearance, and we keep nothing about which line applied. If your health changes, stop and check with your healthcare professional again.

Reckoner coaches your training. It doesn't diagnose or treat injuries, so follow your clinician's advice first. While you let it keep injury details, it can train around a sore or injured area you tell it about: gentler versions of the lifts that load it, or none of them at all, and when you say you are ready to train it again, it brings those lifts back a little lighter. Prehab is strength work for the joints you pick, built into your warm up. Neither is a treatment, and neither is a promise about injury. If you keep your health answers to yourself, it keeps no injury details and you confirm you are fit to train instead. Say that no after setup and you are asked to confirm on your next visit. Until you do, no new week is written for you and nothing new goes to your watch. The week you already have stays on it.

Reckoner gives you a way to say so in the app: flag pain, a swap, too hard, or a skip, and leave a note. A flagged day is deliberately held back from automatic progression. Use it. The engine cannot account for what you never tell it.

What we promise, and what we do not

Reckoner is provided as it is. We are building it in the open and running it on a single rented server, so within reason we do not promise:

• Availability. There is no uptime commitment. It will go down for maintenance, for deploys, and sometimes for reasons we did not plan.
• That it stays the same. Features can change, move or disappear, and the way the engine progresses your lifts is exactly the kind of thing that changes as it gets better.
• Results. Nobody can promise you a stronger squat. What you get out depends on what you do, how you recover, and a great deal that no program controls.
• That the numbers are right for you. Standards, calorie targets and estimated one-rep maxes are population models applied to the handful of values you gave us.
• That it runs forever. If we have to stop the service we will give you reasonable notice and time to export your training log first.

What we do commit to: the data handling set out in the privacy policy, an export you can take at any time, and a deletion that genuinely deletes.

Your account and your data

Your training log is yours. We claim no ownership of what you record, we do not sell it or advertise against it, and we share it with nobody beyond the services that run Reckoner for us. You give us permission to store and process it to run the service, which means showing it back to you and feeding it to the engine that writes your next week, and, only while Learn from my training is on, to keep the de-identified copy described below. What we hold, why, and for how long is the privacy policy, and it is part of this agreement. So is the cookie policy, which lists every cookie the site sets and everything else it keeps in your browser.

Analytics is optional and refusing it costs you nothing. Reckoner asks once whether it may count how the site is used, and the answer is remembered. Every feature works the same either way, nothing is withheld from you for saying no, and you are not asked again unless you go looking for the setting. Withdrawing later is as easy as accepting was, and both are on the cookie policy page.

Reckoner logs the coaching decisions it makes for you and what you did about them, because that is how it coaches you rather than repeating itself. While Learn from my training is on, it also keeps a de-identified copy of your training records to make the coaching better for everyone, and your health answers join that copy only if you say yes to them separately. Both switches are on the Account page, and turning either off changes nothing about your plan, your weights or your history. That copy carries no name, no email address, no account id and nothing you typed, and it is used for one thing: checking and improving how Reckoner coaches, across everyone who trains with it. It is never given to anyone outside Reckoner and the services that run it for us, and only totals across at least ten people, which can never point to one person, are ever shared beyond that. We do not sell it. The full description, including what the copy holds and what deleting your account does to it, is in the privacy policy.

You are responsible for the accuracy of what you enter. Reckoner acts on the numbers it is given, so a bodyweight typed in the wrong unit or a set logged at the wrong load moves next week's plan accordingly.

Keep a copy of anything you would hate to lose. Deletion is immediate and we never restore a deleted account, which is the point, and it cuts both ways. A deleted account can remain in a backup for up to 30 days until that backup expires, and the backups exist only to recover the service if the server is lost.

Video from YouTube

Some pages carry a short video from a YouTube channel we choose, credited to that channel. Nothing about you reaches YouTube from that page until you choose to press play. The picture you see before that is a copy we host ourselves.

Press play, and the video and its player load directly from YouTube. That is Google's own service, not ours, and it runs under YouTube's own terms and privacy policy rather than this one. YouTube may set cookies in your browser once you do, and it will see your IP address and which video you played. If you are already signed in to a YouTube or Google account in that browser, YouTube will recognize you as that account.

Pressing play is the only choice we ask of you here, and there is no separate box to accept. We choose the video. What YouTube can set is named on the cookie policy, which points to YouTube's own list of them.

Telling us what is wrong

You can report a bug or ask for a feature from inside Reckoner, and one person reads all of it and answers with a reason, including when the answer is no.

What you send through the board is published right away, in your own words. We do not turn it into a summary first, and it may be visible to other people before anyone at Reckoner has read it.

If you have chosen to make your display name public, it will appear with your submission. Your founding member number may also appear if you have one. Your email address never appears on the board.

By sending something through the board, you give us permission to publish it, make small edits so it is clear to other readers, and remove it from the board if needed. You can also ask us to remove one of your submissions. Deleting your account removes all of your submissions from the board.

The board is not a messaging system. There are no replies, threads, or private messages between athletes. The only thing another athlete can do to your submission is vote for it.

Keep it about Reckoner. Do not use the board to harass someone or share another person's personal information. What you write is public, so write it with that in mind.

Nothing here is a promise to build what you ask for. An item can sit on the board for a long time, and one of the four statuses is that we are not doing it. What we do promise is that you get an answer with a reason, and that it is visible rather than quietly filed.

What you may not do

• Use another person's account, or let another person use yours.
• Use the report form, a feature request or a board vote to harass anyone, to advertise, or to send personal information about somebody else. It reaches a person, so treat it as one.
• Attack the service: break into accounts that are not yours, probe for holes beyond what a normal client does, or try to knock it over. Finding something and telling us at hello@reckoner.fit is welcome and is not this.
• Automate against the API in a way that degrades it for anyone else, or work around the rate limits on sign-in and pairing.
• Resell the service, or run it as a paid coaching product for other people under your one account.
• Use it for anything unlawful.

Your @handle

Your @handle is unique to you. You can change it once in 12 months; the old one is held for you for 90 days, then anyone may take it. We may ask you to change a handle that pretends to be someone else, uses a name you have no right to, or breaks the rules on what you may write. We tell you first, and you choose the new one.

Sharing a plan

If you share a plan, the plan sharing terms apply as well: what may be shared, what may not, and what we may do when a page breaks the rules. How to share a plan safely says the same in plain words.

Ending it

You, at any moment: the Account page deletes the account, the profile, the whole training history, every paired watch's token and your waitlist entry, immediately, with nothing kept back to restore you from. What stays in the de-identified set can no longer be connected to you. You do not need a reason and you do not need to ask us.

Us: we may suspend or close an account that breaks these terms, or that puts the service or another athlete at risk. Where it is fair to do so we will tell you first and give you a chance to put it right, and we will give you a way to export your log before it goes. We may also close accounts if we stop running Reckoner altogether, with the notice described above.

Liability

Reckoner is free, and there is a limit to what a free service can carry. To the fullest extent the law allows, we are not liable for lost training time, lost data, or indirect or consequential loss, and our total liability for any claim connected to Reckoner is limited to the amount you have paid us, which today is nothing.

Two things that limit does not touch, because it cannot and should not:

• Death or personal injury caused by our negligence, and fraud or fraudulent misrepresentation. Nothing in these terms excludes or restricts either.
• Rights your national consumer law gives you as a consumer. If a clause here conflicts with one of them, that law wins and the rest of these terms carry on.

Changes to these terms

If these terms change, the date at the top changes with them, and material changes will be announced in the app before they take effect. Carrying on with Reckoner after that is acceptance. If you would rather not accept, the Account page is always there.

Governing law

These terms are governed by Dutch law, and the courts of the Netherlands have jurisdiction. If you are a consumer resident elsewhere in the EU, this does not deprive you of the protection of the mandatory consumer law of your own country, and you may bring proceedings there.

If something has gone wrong, email hello@reckoner.fit first. A reply is faster than a procedure, and it is read by the person who can actually fix it.
