Effective date: September 17, 2026
1. Who we are
LeanBytes UG (haftungsbeschränkt), Sindelfingen, Germany. Represented by Stephan Arenswald. Registered at the Amtsgericht Stuttgart under HRB 804213. Contact: legal@leanbytes.io. Our postal address is in the Imprint.
These Terms cover the apps and services we make (“the Services”). They apply when you buy or use any of them.
2. Your licence
You may install and use the Services on devices you own or control, for personal, professional and commercial purposes alike. The licence is non-exclusive and non-transferable. The Services themselves — their code, design and branding — remain ours.
How far the licence reaches. Your licence covers the number of people, seats or devices stated at the point of purchase. Where nothing is stated, it covers you and the devices you use. Buying one licence does not license an organisation; for that, ask us.
What you make stays yours. You keep whatever rights you already hold in the content you bring to the Services and in whatever you produce with them. We claim none of them and place no restriction on selling, publishing or distributing your work. Rights belonging to other people in material you bring with you are untouched by this and stay governed by whatever licence you hold for them.
What you may not do. Rent, lease, resell or sublicense the Services; remove proprietary notices; or use the Services unlawfully. You may not copy, modify, reverse engineer, decompile or disassemble them, except where mandatory law permits it whatever a contract says — for instance to make a backup, to study how they work, or to achieve interoperability.
Open-source software. Where an app, or a component within one, is distributed under an open-source licence, that licence governs it and prevails over this section for the software it covers. Nothing here is intended to restrict a right that such a licence grants you.
Ideas you send us. If you send us a suggestion or a feature request, we may use it for any purpose and owe you nothing for it.
That covers the idea itself. It does not cover anything you send us to illustrate a problem. We treat that as yours and as confidential, use it only to look into the issue you reported, and delete it once we are done.
3. Services that run on our servers
Some features do their work on our servers rather than on your device, and some need to keep data for a while so the feature can work at all.
You will always know when that happens. A feature that sends your content off your device says so where you use it, and names any third party involved — a translation or AI provider, for example. Nothing leaves your device in the background. Where that is the case:
- You allow us to store and process your content for the sole purpose of providing that feature. We take no other rights in it, and the permission ends when the content does.
- We keep your content while you are entitled to use the feature. When that entitlement ends — your subscription ends, you close your account, or you delete the content — we delete what we hold within a reasonable period, unless the law requires us to keep it.
- We do not use your content to train AI models, and we do not permit any provider we use to do so. Our privacy policy sets out what we hold and for how long.
- You are responsible for holding the rights to what you send us and for it being lawful. We may remove content that is not, and suspend a service being used unlawfully or in a way that degrades it for other people.
- Server-based features are provided as available, and we do not promise uninterrupted access unless we have separately agreed a service level with you. That does not affect our obligation to provide the paid features you bought, or your remedies if we fail to.
Your own cloud account. Where an app stores or shares data through a cloud account of yours rather than ours, that data stays in your account under your agreement with that provider. We receive no copy of it, and cannot restore what you or the provider delete.
4. Buying
Purchases are processed through the platform or reseller you buy from — the App Store, or a reseller such as Lemon Squeezy. They take your payment, handle tax and issue your receipt. Who the seller of record is for your particular transaction is identified at checkout and on your receipt; it differs between platforms and between countries. We never receive or store your card or bank details.
The total you pay, including any tax, is shown before you confirm the purchase.
Subscriptions. A subscription renews automatically until you cancel. You may cancel at any time to stop the next renewal. Cancellation takes effect at the end of the current paid period, unless consumer law or the seller’s terms let you end it sooner. Any mandatory right to earlier termination or a proportionate refund is unaffected. Cancel through the seller — your Apple account settings, or the reseller’s customer portal. Ask us and we will help.
Free trials. Where we offer a free trial we will tell you, before it starts, how long it runs and what happens at the end. If it turns into a paid subscription we will say so beforehand, and cancelling before it ends costs you nothing. We may change or withdraw a trial offer before you take it up, and may end a trial early if it is being misused.
Refunds and withdrawal. Refunds, and any statutory right of withdrawal you have, are handled through the platform or reseller you bought from, under their terms. If you have trouble, contact us and we will help you reach them.
5. What you get, and what changes
The Services must work as described when you get them. Where they do not, you have the remedies your consumer law gives you, and nothing in these Terms limits them.
Updates. For a paid subscription we provide the updates, security updates included, needed to keep the Services working as described for as long as the subscription runs. For a one-time purchase we do so for the period you can reasonably expect, given the type and purpose of the product and the circumstances of the sale.
Changes to paid features. We may change what a paid plan includes where there is a good reason — adapting to a new operating system or platform requirement, a change in law, a security fix, or a significant change in how the Services are used. We will not materially reduce what your paid plan includes without telling you at least 30 days beforehand, in a form you can keep, and you may then cancel and get back the unused part of what you paid. You have at least 30 days to do that, counted from our notice or from the change itself, whichever comes later.
Changes to free features. Free features may change or be discontinued at any time. Where a change materially reduces a free feature we will say so in the app and in the release notes, where that is reasonably possible.
6. Changes to these Terms
We update these Terms from time to time. A new version applies to purchases made on or after its effective date.
If you already hold a licence or a subscription, the Terms you agreed to keep applying to it, renewals included. We will not change them for you unless you agree to the change, or unless the law requires it — and then only from the date the law requires.
7. Liability
We are liable without limitation for intent, gross negligence, and negligently caused injury to life, body or health. Liability under mandatory product liability law, for fraudulently concealed defects, and under any guarantee we expressly give, is unaffected.
In other cases of ordinary negligence we are liable only for breach of an essential contractual obligation — one whose fulfilment makes proper performance of the contract possible, and on which you can ordinarily rely. In those cases liability is limited to the foreseeable damage typical of the contract at the time it was concluded.
Otherwise liability for ordinary negligence is excluded. These limitations apply equally to our legal representatives and to anyone we engage to perform our obligations.
Nothing in this section excludes or limits liability where doing so is prohibited by applicable law.
8. If you are not a consumer
This section applies where you acquired the Services in the course of your trade, business or profession. It does not apply if you are an individual who acquired them mainly for private purposes, even if you sometimes use them for work.
- Rights the law gives only to consumers, including any right of withdrawal, do not apply to you.
- Our liability for ordinary negligence does not extend to lost profit, lost revenue or other indirect loss. It is otherwise as set out in Section 7, whose first paragraph is unaffected.
- You have twelve months from delivery to bring a claim for a defect before a court, rather than the longer period the law would otherwise give you. Claims under the first paragraph of Section 7 are not affected.
- Where the law permits such an agreement in advance, the courts of Stuttgart have exclusive jurisdiction.
9. Ending the agreement
You may stop using the Services at any time. For subscriptions, see Section 4.
We may suspend or end your access if you seriously breach these Terms. Where the breach is one you can put right, we will tell you and give you reasonable time to do so first, unless it is a breach that needs acting on immediately. Otherwise a perpetual licence you have paid for stays yours, and a paid period you have already paid for runs to its end.
10. Apps from the Apple App Store
For apps obtained from the App Store, Apple’s end-user licence agreement governs your licence to use the app, and we are the licensor under it. These Terms govern the rest of our relationship — what you make with the Services, how they change, and support.
Both documents limit our liability and disclaim warranties. For an App Store purchase we will not rely on Apple’s agreement to give you less than these Terms give you. This does not change the conditions Apple sets on how you may use an app from the App Store — those are between you and Apple, and are not ours to set aside.
11. Law and disputes
German law applies. If you are a consumer, the mandatory consumer-protection rules of the country you live in also apply, and you may bring proceedings there.
12. General
Anything we have specifically agreed with you takes precedence over these Terms, whenever we agreed it. Otherwise these Terms, together with anything agreed at the point of purchase, are the whole agreement between us. If a provision turns out to be invalid, the rest stands and the statutory rule takes its place. Not enforcing a provision is not a waiver of it. These Terms are written in English and the English version governs.
