Terms of Service

Effective date: March 2, 2026

1. Provider

These Terms of Service govern your use of the apps and digital services (“the Services”) provided by:

LeanBytes UG (haftungsbeschränkt) Goldmühlestraße 65 71065 Sindelfingen Germany

Represented by: Stephan Arenswald Registered in the Handelsregister of the Local Court (Amtsgericht) Stuttgart: HRB 804213 Contact: legal@leanbytes.io

2. Acceptance of Terms

These Terms form a legally binding agreement between you and LeanBytes. Before using the Services, you must be given a clear opportunity to read these Terms and confirm your agreement — for example, by checking a box or tapping an acceptance button at first launch or at the time of purchase.

These Terms apply to all users regardless of whether the Services were obtained through the Apple App Store, a direct purchase, or any other distribution channel.

If you do not agree to these Terms, do not use the Services.

3. Description of Service

LeanBytes provides a range of digital products — apps and services — available on various terms, including free, paid, and freemium models.

For free features and free-tier users: LeanBytes may modify, suspend, or discontinue any free feature or service at any time. Where reasonably possible, advance notice will be given.

For paid subscriptions: LeanBytes will not make material adverse changes to the features or functionality included in your subscription without giving at least 30 days’ prior notice. If LeanBytes makes such a material change, you have the right to terminate your subscription and receive a pro-rated refund for the remaining prepaid period, unless the change is required by law or is necessary to address a security risk.

4. License Grant

Subject to these Terms, LeanBytes grants you a limited, non-exclusive, non-transferable, revocable license to use the Services on devices you own or control, solely for personal, non-commercial use.

You may not:

  • Copy, modify, or create derivative works of the Services
  • Reverse engineer, decompile, or disassemble the Services
  • Rent, lease, lend, or sublicense the Services
  • Remove or alter any proprietary notices or labels on the Services
  • Use the Services for any unlawful purpose or in violation of any applicable law

5. Purchases and Payments

5.1 General

All prices are stated at the time of purchase and include applicable VAT where required by law. Prices may vary by region and distribution channel.

5.2 One-Time Purchases

Certain versions or features of the Services may be available for a one-time payment. Upon payment, you receive a perpetual license to use the purchased version of the Services, subject to these Terms.

5.3 Subscriptions

Certain features or access tiers require a recurring subscription.

Auto-renewal: Subscriptions renew automatically at the end of each billing period at the then-current subscription price. You will be charged automatically at the start of each renewal period unless you cancel.

Cancellation: You may cancel your subscription at any time. To cancel, use the cancellation mechanism provided by the platform through which you subscribed:

  • Apple App Store: through your Apple ID account settings
  • Lemon Squeezy: through the customer portal or cancellation link provided at purchase

Cancellation takes effect at the end of the current billing period. No partial refunds are provided for unused time within a billing period, except as required by applicable law or the platform’s own policy.

Notice period: For subscriptions that renew annually, you may cancel at any point up to the day before renewal. No advance notice period exceeding three months before the end of the contract term will be required.

Price changes: If LeanBytes changes the subscription price, you will be notified at least 30 days in advance. If you do not agree to the new price, you may cancel your subscription before it takes effect, and your existing subscription will continue at the old price until the end of the current billing period.

Extraordinary termination: Both parties retain the right to terminate a subscription contract for good cause (wichtiger Grund) at any time without notice, pursuant to § 314 BGB. LeanBytes will exercise this right only in cases of material breach of these Terms. In such cases, LeanBytes will provide a pro-rated refund for the remaining prepaid period, unless the termination is due to your breach.

5.4 In-App Purchases

Additional features, content, or functionality may be available for purchase within the Services. All in-app purchases are final unless otherwise stated or required by applicable law.

5.5 Purchases via Apple App Store

If you obtain the Services, a subscription, or an in-app purchase through the Apple App Store, the transaction is processed by Apple Inc. Apple acts as the merchant of record. Payment, billing, refunds, and dispute resolution are governed by Apple’s terms and conditions. LeanBytes does not process or store your payment information for App Store transactions.

5.6 Direct Purchases via Lemon Squeezy

If you purchase a license or subscription directly, the transaction is processed by Lemon Squeezy (operated by Lemon Squeezy, LLC), which acts as the merchant of record. Lemon Squeezy’s terms and privacy policy govern the commercial transaction. LeanBytes does not receive or store your payment or full billing details.

6. Right of Withdrawal

For purchases through Apple App Store or Lemon Squeezy: As these platforms act as merchant of record, their respective right-of-withdrawal and refund policies apply. Please consult Apple’s or Lemon Squeezy’s terms for your statutory withdrawal rights.

For any purchases made directly with LeanBytes (if applicable): EU and German consumers have a statutory right to withdraw from a distance contract within 14 days of conclusion of the contract, without giving reasons (§ 355 BGB).

Exception for digital content delivered immediately: Pursuant to § 356 Abs. 5 BGB, the right of withdrawal expires before the end of the 14-day period if:

  1. You have expressly consented to performance beginning immediately before the withdrawal period has expired; and
  2. You have acknowledged that you thereby lose your right of withdrawal upon commencement of performance.

This acknowledgment is requested explicitly at the time of purchase.

7. Conformity and Updates for Digital Products

In accordance with §§ 327 ff. BGB (implementation of EU Directive 2019/770 on digital content and digital services), LeanBytes is obligated to ensure that the Services conform to the contract at the time of delivery and, where applicable, throughout the supply period.

For subscriptions: LeanBytes will provide updates — including security updates — necessary to maintain the Services’ conformity with the contract for the duration of your active subscription.

For one-time purchases: LeanBytes will provide updates necessary to maintain conformity for a period that is reasonable given the type and nature of the Services and the price paid.

If the Services do not conform to the contract, you have the statutory remedies available under §§ 327i ff. BGB, including the right to have the non-conformity remedied, a price reduction, or termination of the contract.

These statutory rights are not excluded or limited by any other provision of these Terms.

8. Intellectual Property

The Services and all associated content, code, design, graphics, and branding are owned by LeanBytes or its licensors and are protected by applicable intellectual property laws. These Terms grant you only a limited right to use the Services. No ownership rights are transferred.

9. Prohibited Uses

You agree not to use the Services to:

  • Violate any applicable law or regulation
  • Infringe the rights of any third party, including intellectual property rights
  • Transmit any malware, spyware, or other harmful code
  • Attempt to gain unauthorized access to any system, network, or data
  • Interfere with or disrupt the integrity or performance of the Services

10. Warranties

LeanBytes warrants that the Services will conform to the contract at the time of delivery, in accordance with §§ 327 ff. BGB.

Beyond the statutory conformity obligations set out in Section 7, LeanBytes makes no additional warranties. In particular, LeanBytes does not warrant that the Services will be error-free, uninterrupted, secure, or meet any specific performance criteria beyond those expressly stated.

Nothing in these Terms excludes or limits the statutory warranty rights of consumers under German or EU law.

11. Limitation of Liability

The following cannot be excluded or limited under applicable law, and nothing in these Terms does so:

  • Liability for death or personal injury caused by LeanBytes’ negligence
  • Liability for intentional misconduct (Vorsatz) or gross negligence (grobe Fahrlässigkeit) by LeanBytes, its legal representatives, or its agents (§ 278 BGB)
  • Liability under the German Product Liability Act (Produkthaftungsgesetz)
  • Any other liability that cannot be excluded or limited under §§ 307–309 BGB or other applicable mandatory law

To the extent permitted by German law, LeanBytes’ liability for simple negligence (einfache Fahrlässigkeit) is limited to foreseeable, typical damages arising from breach of a material contractual obligation (Kardinalpflicht). LeanBytes is not liable for indirect, incidental, or consequential damages arising from simple negligence.

12. Changes to These Terms

LeanBytes may update these Terms from time to time.

For free-tier users and one-time purchasers: Material changes will be communicated with at least 30 days’ notice — for example, via in-app notification or email where available. Continued use of the Services after the effective date of the updated Terms constitutes acceptance.

For active subscription holders: Material changes to these Terms require your explicit consent or, alternatively, notification with a right to terminate. If you receive notice of a material change and do not agree, you may terminate your subscription before the change takes effect and receive a pro-rated refund for the remaining prepaid period.

13. Termination

Termination by LeanBytes: LeanBytes may suspend or terminate your access to the Services for material breach of these Terms. For subscription contracts, termination for cause (§ 314 BGB) is available to both parties at any time where a material reason exists. Termination without cause of a paid subscription requires reasonable notice.

Termination by you: You may terminate these Terms at any time by ceasing to use the Services and deleting them from your devices. For subscriptions, see Section 5.3 for cancellation procedures.

Upon termination, your license to use the Services is immediately revoked. Provisions that by their nature survive termination — including intellectual property, liability, and governing law — remain in effect.

14. Dispute Resolution

EU Online Dispute Resolution (ODR): The European Commission provides a platform for online dispute resolution for consumer disputes arising from online contracts, accessible at: https://ec.europa.eu/consumers/odr

Consumer Arbitration (VSBG): LeanBytes is not obligated to participate in consumer dispute resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle) pursuant to the Verbraucherstreitbeilegungsgesetz (VSBG), and does not voluntarily participate in such proceedings.

15. Governing Law and Jurisdiction

These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law rules.

For disputes with consumers habitually resident in another EU member state, the mandatory consumer protection provisions of that member state also apply, and consumers may bring proceedings in the courts of their country of habitual residence in accordance with EU Regulation 1215/2012 (Brussels I Regulation), Art. 18.

The courts of Stuttgart shall have non-exclusive jurisdiction for disputes arising from or related to these Terms, subject to the above.

16. General Provisions

Severability: If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions continue in full force. The invalid provision shall be replaced by the applicable statutory rule (§ 306 BGB).

Entire agreement: These Terms, together with any product-specific terms provided at the time of purchase, constitute the entire agreement between you and LeanBytes regarding the Services.

Contract language: The contract is concluded in English.

No waiver: Failure by LeanBytes to enforce any provision of these Terms shall not constitute a waiver of future enforcement of that provision.
