ClassTiles

Terms of Use

ClassTiles · End-user licence agreement

Version: 19 July 2026 · Provider: Stefan Venekamp · Applies from: app version 1.0

These Terms of Use govern the relationship between you (the “User”) and the provider of the app ClassTiles (“Notenverwaltung”), Stefan Venekamp (the “Provider”), regarding the use of the app on iPhone, iPad and Mac. Please read them carefully before use.

Important allocation of roles (please read first). ClassTiles is distributed through the Apple App Store. The purchase, payment and withdrawal process is concluded with Apple (Apple as distribution partner / “merchant of record”), not with the Provider. These Terms of Use govern the usage/licence relationship between you and the Provider. Your statutory consumer rights vis-à-vis Apple (e.g. withdrawal, refund) and the statutory warranty for digital products (§§ 327 et seq. of the German Civil Code, BGB) remain unaffected by these terms (§ 6).

§ 1 Scope, contracting party, incorporation

  1. The provider and contracting party to this usage agreement is:
Stefan Venekamp, c/o Block Services, Stuttgarter Str. 106, 70736 Fellbach, Germany · Email: classtiles@icloud.com
(complete provider identification: Legal Notice).
  1. These Terms of Use are made accessible to you in a reasonable manner before purchase on the App Store product page (where they are filed as the licence agreement); you can also view them at any time within the app under “Settings → Legal” and retrieve and save them in reproducible form at https://classtiles.de/nutzungsbedingungen. By purchasing the app via the App Store and using it, you accept these Terms of Use as binding.
  2. Relationship with Apple. The contractual acquisition process (purchase price, invoice, VAT, withdrawal, refund) runs exclusively through Apple under the Apple Media Services Terms and Conditions. These Terms of Use take the place of Apple's standard licence (“Licensed Application End User License Agreement”) as the Provider's own end-user licence agreement; to the extent that Apple's mandatory minimum terms apply, the clarifications in § 9 apply in addition.
  3. Deviating or supplementary terms of the User do not become part of the contract unless the Provider expressly agrees to their application in writing.
  4. Legal capacity. The app is aimed at teachers and presumes that you have full legal capacity or that you use the app with the consent of your legal guardian. It is not directed at use by children.

§ 2 Subject matter of the contract and description of services

  1. ClassTiles is an app for the local management of grades, student data and documentation as well as for lesson organisation (including calendar, lesson planning, seating and group plans). The data is stored primarily locally on your device.
  2. Optional functions that you enable yourself:
  1. Free version and full version (in-app purchase). ClassTiles can be downloaded and used free of charge. In the free version you can create one class and use all features without restriction within it; a class in the trash also counts as a created class. The full version removes this limit (unlimited classes) and is acquired as a one-time in-app purchase (no subscription) exclusively through Apple; the price is shown to you in the App Store before purchase. The purchase is tied to your Apple ID and can be restored on further devices using the same Apple ID and, after reinstalling, via “Restore Purchases”. Apple Family Sharing is not enabled for this purchase. Data you have already recorded is never locked, hidden or deleted as a result of the free version’s limit; export, backup and synchronisation remain available at all times regardless of the full version.
  1. The scope of services owed is determined by the functionality of the app version actually installed and the description on the App Store product page. Functions that depend on third-party services (in particular Apple iCloud or a WebDAV server you choose) are available only subject to the availability and terms of those third parties; the Provider does not owe the availability of these third-party services themselves. The functioning of the app-side connection to such services remains part of the scope of services owed.
  2. Supporting function. ClassTiles serves to support grade management. Responsibility for the accuracy, completeness and lawful use of the data entered — in particular the grades — remains with the User. (Where a technical defect of the app persists, § 6 applies.)

§ 3 Rights of use (licence)

  1. The Provider grants you a non-exclusive, non-transferable right to use ClassTiles for the term of the contract as intended on Apple devices that you own or control — subject to the Usage Rules of the Apple Media Services Terms and Conditions. Use within Apple's Family Sharing and volume purchase programmes is permitted to the extent Apple provides for it for the app or the respective purchase; Family Sharing is currently not enabled for the full-version purchase.
  2. The app is protected by copyright. All rights in the app, its source/object code, its design and its content (excluding the data you record, which belongs to you or to the responsible controller) remain with the Provider or its licensors.
  3. You may not rent, lend, sell, sublicense or otherwise make the app available to third parties; you may not modify it — subject to the mandatory statutory powers under §§ 69d, 69e of the German Copyright Act (UrhG) — and you may not remove copyright or protective-right notices. Reverse engineering, decompiling or disassembling is permitted only to the extent that a statute mandatorily allows it (in particular § 69e UrhG for the purpose of establishing interoperability) and within the scope regulated there.

§ 4 Your data, your data protection responsibility, obligations of use

  1. You decide which data you record in the app. For the personal data you record (in particular student, grade and documentation data), you yourself — as the teacher, or your school / school authority — are the controller within the meaning of the GDPR. The Provider has no access to this data, does not process it and is not a processor (for details see the Privacy Policy, https://classtiles.de/en/privacy).
  2. You are responsible for ensuring that your use of ClassTiles is lawful. In particular you ensure that
  1. The “Class Tasks” sharing function. A share link on the “anyone with the link” principle grants any person holding that link read and write access to the shared board. Only task data (title, description, priority, due date, status) is shared, in a separate, isolated database — structurally no grades and no student records. You alone decide whom you pass the link to and bear responsibility for that. No real names or sensitive data of students should be entered in shared boards.
  2. You will refrain from any unlawful or abusive use of the app.
  3. Review of exports. The User is responsible for reviewing data exported from the app (e.g. PDF, XLSX or JSON export) before making further use of it.

§ 5 Availability, updates, support

  1. Updates. For the period you can reasonably expect given the nature and purpose of the app, the Provider supplies the updates necessary to maintain conformity with the contract (including security updates) — in line with § 327f BGB. You will be informed of available updates in the usual way (App Store).
  2. Support. The Provider alone (not Apple) is responsible for maintenance and support of the app. Please address support enquiries to classtiles@icloud.com. No particular response or availability standard is assured beyond mandatory statutory requirements.
  3. Third-party services. The Provider is not responsible for the availability, scope of functions and terms of Apple iCloud or of a WebDAV server you choose.
  4. Availability. There is no entitlement to uninterrupted availability of the app or of individual functions at all times. Functionality may be affected by future changes to the operating system or to interfaces provided by Apple; the update obligation under paragraph 1 remains unaffected.

§ 6 Warranty (statutory liability for defects)

  1. The statutory liability for defects in digital products under §§ 327 et seq. BGB applies in its respective mandatory form.
  2. These Terms of Use neither exclude nor limit your statutory warranty and consumer rights. Where you as a consumer are entitled to mandatory rights — irrespective of against whom they are directed — these continue to apply without restriction; provisions in these terms to the contrary do not apply to consumers.
  3. Allocation of roles. The acquisition/supply transaction is concluded with Apple as your contracting party (§ 1(3)); you therefore assert the statutory rights in respect of defects arising from that acquisition (§§ 327 et seq. BGB) against Apple. § 9(4) applies in addition (refund of the purchase price by Apple). Independently of this, the Provider is bound by the obligations under these Terms of Use — in particular the update obligation under § 5(1) — as well as by any mandatory statutory obligations that apply to it directly as the developer of the app; paragraph 2 applies in this respect.

§ 7 Liability

  1. The Provider is liable without limitation
  1. In the case of ordinary negligence, the Provider is liable only for the breach of a material contractual obligation — that is, an obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely. Material contractual obligations in this sense are, in particular, the provision of the contractually agreed core functions (local recording, storage and display of your data) and the preservation of the integrity of the data you store on the device by the app in intended operation. In such cases, liability is limited to the typical, foreseeable damage.
  2. Any further liability of the Provider for damages is otherwise excluded.
  3. Data backup / loss of data. The app stores data primarily locally; synchronisation and backups are optional functions controlled by you. You are yourself responsible for regular data backups appropriate to your data holdings. If a loss of data occurs within the scope of liability under paragraphs 1 and 2, it must be taken into account when assessing the compensable damage that, with proper, regular data backups on your part, the damage would typically have been limited to the effort of restoring the data from such a backup (the legal principle of § 254 BGB). The above limitation does not apply in the cases of paragraph 1 (in particular intent, gross negligence and injury to life, body or health); in those cases the Provider is liable without limitation under the statutory provisions.
  4. The above provisions do not entail any change of the statutory burden of proof to your detriment.

§ 8 Term and termination

  1. The right of use exists for the duration of the intended use of the app.
  2. The right of either party to terminate for good cause remains unaffected. In the event of a significant breach of these Terms of Use (in particular § 3 or § 4) that is not remedied despite a request to do so, the Provider may terminate the right of use; you may end your use at any time by uninstalling the app. Fees already paid via Apple are governed by Apple's terms.
  3. Upon termination, the right of use ends. Your locally stored data remains unaffected by this (the Provider has no access to it); export and deletion of your data remain within your control at all times (see the Privacy Policy).

§ 9 Apple as third-party beneficiary · Apple minimum terms

Because these Terms of Use take the place of Apple's standard licence as the Provider's own end-user licence agreement, the following clarifications, mandatorily required by Apple, apply in addition. You and the Provider acknowledge that:

  1. This licence agreement is concluded solely between you and the Provider, not with Apple; the Provider alone — not Apple — is responsible for the app and its content.
  2. The right of use is limited to use on Apple devices that you own or control and is not transferable (§ 3).
  3. The Provider alone is responsible for maintenance and support; Apple has no obligation whatsoever in this respect.
  4. The Provider is responsible for the warranty; if the app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price to you; beyond that, Apple has no warranty obligation whatsoever.
  5. Claims in connection with the app — including product liability, non-compliance with legal/regulatory requirements, and claims arising under consumer protection, data protection or similar provisions — are directed against the Provider, not against Apple.
  6. In the event of third-party claims alleging infringement of intellectual property rights by the app, the Provider alone is responsible for the investigation, defence, settlement and discharge of such claims.
  7. You represent that you are not located in a country subject to an embargo or designated by the US government as a country “supporting terrorism” and that you are not listed on any US list of prohibited or restricted parties (§ 10).
  8. You will comply with applicable third-party terms when using the app.
  9. Apple and Apple's subsidiaries are third-party beneficiaries of this licence agreement and are entitled to enforce it against you.
  10. For questions, complaints or claims regarding the app, please contact the Provider: Stefan Venekamp, classtiles@icloud.com (postal address: see the Legal Notice).

§ 10 Export control and sanctions law

You confirm that you will not use or export the app in breach of applicable export control, sanctions or embargo law (in particular that of the EU and the USA), and that you will comply with the representations set out in § 9(7).

§ 11 Changes to these Terms of Use

  1. The Provider may adapt these Terms of Use where this is necessary (e.g. due to a change in the legal situation, supreme court case law, changed Apple requirements, or new/changed app functions) and where the change does not unreasonably disadvantage you.
  2. The Provider will inform you of material changes by suitable means (e.g. a notice in the app). A material change takes effect only with your consent; if you do not consent, you may continue to use the app to its previous extent or end your use. Mere continued use does not automatically constitute consent.

§ 12 Choice of law, consumer dispute resolution, final provisions

  1. Choice of law. The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). Mandatory consumer protection provisions remain unaffected: if, as a consumer, you have your habitual residence in another state (in particular within the EU/EEA), you may additionally rely on the more favourable mandatory provisions of the law of your state of residence; this choice of law does not deprive you of that protection (Art. 6 Rome I Regulation).
  2. Place of jurisdiction. For actions against you as a consumer, the court at your place of residence has jurisdiction; you may bring proceedings against the Provider either at the Provider's general place of jurisdiction or at the court of your place of residence. Mandatory jurisdictions remain unaffected.
  3. Consumer dispute resolution (§ 36 VSBG). The Provider is neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
  4. Severability. Should a provision of these Terms of Use be or become invalid, the validity of the remaining provisions remains unaffected; the invalid provision is replaced by the statutory provision (§ 306 BGB). Vis-à-vis consumers, disadvantageous clauses will not be upheld by way of a validity-preserving reduction.
  5. Language of the contract. The language of the contract and of communication is German. Where the Provider supplies translations, the German version prevails in the event of discrepancies, unless mandatory law of your state of residence prescribes the language of your state of residence.

This English text is a convenience translation. The German version is the legally binding one (see § 12(5)).
