Terms and Conditions

Georg Flossmann, trading as “leanframe”, Ickelsamerstraße 35, 81825 Munich, Germany (“leanframe”, “we”). Version of 1 November 2026.

This English version is provided for information only. The German version is legally binding.

1. Scope

  1. These terms apply to all contracts for the use of the leanframe software between leanframe and the customer.
  2. Our offer is directed exclusively at businesses within the meaning of Section 14 of the German Civil Code (BGB), legal entities under public law and special funds under public law. We do not enter into contracts with consumers.
  3. Deviating or supplementary terms of the customer apply only if we expressly agree to them in text form.

2. Services

  1. leanframe is appointment booking software that we provide as an online service (“software as a service”). Depending on the plan, it includes in particular a booking chat for the customer’s website, a booking page without chat, a calendar with staff, confirmations and reminders by email, links to reschedule and cancel, a waitlist, tasks for the business with questions to end customers by email, aftercare after the appointment (review request, reminder of a follow-up appointment) with the end customers’ consent, offers and discounts, export and webhooks, an assistant in the portal, answering emails in the customer’s mailbox and a connection to calendars from Google, Microsoft (Outlook, Microsoft 365) and Apple (iCloud).
  2. The exact scope of each plan is stated on the Features and plans page and in the portal at the time of purchase.
  3. The booking chat, the email channel and the portal assistant use an AI language model. They identify themselves as AI, only offer times that are free in the customer’s calendar, and every booking is confirmed by the end customer. AI answers may nevertheless be incomplete or inaccurate. The customer is responsible for ensuring that the opening hours, services, prices and texts in their settings are correct.
  4. The AI only mentions offers and discounts as the customer has entered them in the portal and notes them on the appointment. The customer is responsible for the content and conditions of offers and for billing the end customer; leanframe does not process end customer payments. The AI drafts questions to end customers and replies to emails as suggestions; via the portal they are only sent once a user of the customer sends them or the customer has switched on automatic replies.
  5. We continuously develop leanframe. We may change features as long as the agreed core of the service is preserved and the change is reasonable for the customer.

3. Conclusion of contract and trial

  1. The contract is concluded when the customer registers in the portal and confirms their email address. If we set up access at the customer’s request, it is concluded as soon as an owner accepts these terms on first signing in to the portal. We store the acceptance with name, email address, time and version.
  2. Every new business receives a free 14-day trial with the features of the Plus plan. No payment details are required. The trial ends automatically and does not turn into a paid plan on its own.
  3. The customer books a paid plan in the portal. This creates a subscription at the prices shown there.

4. Prices and payment

  1. The prices at the time of purchase apply, as shown on leanframe.de/features and in the portal. All prices are net, plus statutory VAT.
  2. The plan fee is payable monthly in advance. Payments are processed by our payment provider Stripe. Invoices are provided electronically.
  3. Add-on packs (for example 100 additional customer chats) are valid until the end of the current billing month and are charged with the next invoice. The customer can switch automatic top-ups on and off in the portal.
  4. If the customer is in default of payment, we may pause access after notice in text form and a period of at least 14 days. The data is retained.

5. Plan limits

  1. Each plan has monthly limits, for example for new customer chats, messages to the portal assistant and users.
  2. The limits are soft: beyond the limit and any add-on packs there is a buffer of 10%. We notify by email at 80% and at 100%.
  3. Once the buffer is used up, new end customers in the chat receive the business’s contact details instead of the assistant. Ongoing conversations, confirmations, reminders and calendar sync always continue.

6. Term, plan changes and cancellation

  1. Subscriptions run monthly and renew by one month at a time.
  2. The customer can cancel at any time with effect from the end of the current billing month, in the portal under Subscription or in text form to us. Fees already paid for the current month are not refunded.
  3. The customer changes plans in the portal. The proration terms shown there apply.
  4. We may terminate with one month’s notice to the end of a month.
  5. The right to terminate without notice for good cause remains unaffected. Good cause for us exists in particular if the customer uses leanframe for unlawful purposes, such as advertising without consent.

7. End without a plan and deletion of data

  1. After the trial or a subscription ends, the booking chat no longer accepts new bookings. The portal remains accessible and the data is retained.
  2. If the customer does not book a plan, we email the administrators after 60 days with the planned closing date. We close the business no earlier than 90 days after the end and at least 25 days after this email.
  3. 30 days after closing, we permanently delete all data of the business. Until then, booking a plan or a message to us is enough to restore everything.
  4. On request, we provide the customer and appointment data in a common format before deletion. Backups expire after their retention period (see the data processing agreement).

8. Customer obligations

  1. The customer keeps their access credentials confidential and only invites people who work for them.
  2. The customer uses leanframe only in accordance with applicable law. They inform their end customers about the processing of their data themselves and enter a link to their privacy policy in the portal for this purpose.
  3. The booking chat is not designed to collect health data or other special categories of personal data (Art. 9 GDPR), such as complaints or diagnoses. The customer does not configure it for this purpose. Where a booking with a health professional in itself allows conclusions about health, the customer ensures the necessary legal basis and informs their end customers. The customer collects health data only in questionnaires (Plus plan) and only in questions marked as confidential, once we have enabled this option; these answers are stored only with the end customer's explicit consent, encrypted and never passed to an AI model. The customer only asks what they need to prepare the appointment, never makes an appointment depend on such information, updates their privacy policy, checks whether a data protection impact assessment is required (Art. 35 GDPR), grants the right to view only to staff who need it and observes their own duties of confidentiality (e.g. Section 203 StGB). leanframe is not intended for statutory records (e.g. patient files).
  4. The customer only uses questions and replies by email for the concerns of the respective end customer, not for advertising or newsletters. leanframe only sends review requests and reminders of follow-up appointments to end customers who consented themselves; the customer does not change the texts so that only satisfied end customers are asked for a review or reviews are rewarded, and adds aftercare to their privacy policy. The customer is responsible for recipients to whom they pass on data by webhook or export.
  5. The customer does not attempt to circumvent security measures, access data of other businesses or overload the services.

9. Availability and support

  1. We aim for an availability of 99% on a monthly average. Announced maintenance and disruptions beyond our control, for example at providers of data centres, AI models or email delivery, are excluded.
  2. We provide support by email on working days.
  3. For troubleshooting, we can open time-limited support access to the business by agreement. Every access has a stated reason, is shown in the portal, is reported to the business by email and can be ended by the business at any time.

10. Liability

  1. We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the Product Liability Act and to the extent of any guarantee given.
  2. In cases of slight negligence, we are only liable for breach of an essential contractual obligation on whose fulfilment the customer may regularly rely. Liability is then limited to the foreseeable damage typical for the contract, at most to the fees for the twelve months before the damaging event.
  3. During the free trial we are only liable for intent and gross negligence, except for injury to life, body or health.
  4. We are not liable for missed appointments or revenue caused by incorrect information in the customer’s settings.

11. Data protection

  1. Where we process personal data on behalf of the customer, we do so as a processor. The data processing agreement with the technical and organisational measures and the list of sub-processors forms part of this contract.
  2. We are the controller for the data of portal users and for billing. Details are in the privacy policy.

12. Changes to these terms and to prices

  1. We announce changes to these terms or to prices by email at least six weeks before they take effect.
  2. The customer may object to the change until it takes effect or cancel as of that date. If they do not object, the change is deemed accepted. We point this out in the announcement.

13. Final provisions

  1. The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods.
  2. If the customer is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Munich.
  3. The contract language is German. This English version is for information only; the German version prevails.
  4. If any provision is invalid, the remaining provisions remain in force.
