Terms of Service
The contract between RetainLens and the studio using it. Short, because the service is short: we read a copy of your check-in data and hand you a list.
RetainLens is not live yet. Nothing on this website is an offer to conclude a contract today. These terms apply from the moment an account is opened for you.
1. Who you are contracting with
Eldridge Kaboth
Bromberger Straße 69
28237 Bremen
Germany
Email: hello@retainlens.com
2. Who may use RetainLens
RetainLens is a business service. You may use it as a business, self-employed person or organisation acting in the course of your trade (§ 14 BGB); it is not offered to consumers, and consumer withdrawal rights therefore do not apply. You must be of full age and entitled to represent the business you sign up for.
3. What the service does
RetainLens reads a copy of your member and attendance data, by CSV upload or a read-only connection to your gym platform, then scores each member against their own attendance baseline, and shows you who is drifting, with the reason. It sends you a weekly summary email if you want one.
The scores are estimates from attendance patterns. They are not advice, medical, legal or financial, and they are not a prediction we stand behind: what you do with a name on the list is your decision, and the conversation with that member is yours.
Every integration is read-only. RetainLens cannot cancel a membership, charge a card, book a class or change a record in your platform.
4. Your account
Keep your account details accurate and your credentials to yourself. You are responsible for what the people you invite do in your account. Tell us as soon as you think someone else has access.
5. Trial, plans and payment
- Every plan starts with a 14-day free trial. No card is required to start it.
- After that, the plan you pick is billed monthly in advance through Stripe. Prices on the website are final: as a small business under § 19 UStG we charge no VAT. If that status ends, VAT is added where it applies and you are told before the next renewal.
- If a trial or a subscription ends without payment, the account goes read-only. Your data stays for 60 days so you can export it or come back, and is deleted after that.
- Price changes are announced at least 30 days in advance by email, and you can cancel before they take effect.
6. Your data, your responsibility
The member data you bring stays yours. In data protection terms you are the controller and we are your processor; the Data Processing Agreement applies to every account and forms part of these terms.
You confirm that you may lawfully share that data with a processor. Do not upload health data, injury notes, body metrics, payment details or anything else in the special categories of Art. 9 GDPR. The product does not ask for those fields, has no place to put them, and they are outside what you may send us.
7. Availability and support
We work to keep the service available and will announce planned maintenance in advance, but we do not promise a specific uptime figure and there is no service level agreement at these prices. Support is by email on German business days; we answer as fast as one person reasonably can.
8. What you may not do
- Resell the service or give access to people outside your business.
- Reverse engineer it, scrape it, or automate access outside a documented interface.
- Try to reach another account's data, or test that boundary without asking us first. If you want to look for holes, write to hello@retainlens.com and we will talk.
9. Term and cancellation
The contract runs monthly and either side may cancel it to the end of the current billing month. You cancel on the billing page yourself. No notice letter, no phone call. We may terminate for good cause, in particular if payment fails repeatedly or section 8 is broken.
10. Liability
We are liable without limitation for intent and gross negligence, for injury to life, body or health, and where German product liability law applies.
For slight negligence we are liable only where a duty essential to the purpose of this contract has been breached, and then limited to the damage typical for such a contract and foreseeable at the time it was concluded. Beyond that, liability is excluded.
In any case, our aggregate liability for slight negligence in a contract year is limited to the fees you paid us in the twelve months before the event.
Data loss: our liability is limited to what restoring a backup you keep yourself would have cost. Export your data regularly; the export is in the product for that reason.
11. Changes to the service and these terms
We may develop the service further, and we may change these terms where there is a good reason: new features, a change in the law, a new provider. You are told by email at least 30 days before a change takes effect. If you object in that window, either side may terminate to the date the change would apply.
12. Final provisions
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Where you are a merchant, a legal person under public law or a special fund under public law, the place of jurisdiction is Bremen.
We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG).
If a provision of these terms is or becomes invalid, the rest stays in force.
