Terms of Service

Last updated: April 2026

§ 1 Scope

(1) These Terms of Service ("Terms") govern the use of the website perimea.app and the mobile application Perimea (hereinafter "Software" or "App"), provided by:

Siegel Resilience, Roberto Siegel, Zur kleinen Bastei 8, 01824 Rathen, Germany (hereinafter "Provider").

(2) Depending on usage, the contracting party is either a consumer (§ 13 BGB) or a business (§ 14 BGB). Unless expressly stated otherwise, these Terms apply equally to both.

(3) Conflicting terms of the user are not recognized unless the Provider expressly agrees to their validity in writing.

§ 2 Subject matter

(1) The Provider supplies the Perimea app for the professional execution of physical security assessments. The app processes all user data exclusively locally on the device ("offline-first"); no server-side storage of content data takes place.

(2) The app is distributed exclusively via the Apple App Store (iOS/iPadOS) and Google Play Store (Android). The respective terms of use and sale of the platform operators (Apple Inc. and Google LLC) apply additionally for the acquisition. The contracting party for the acquisition of the app is the respective platform operator.

(3) The website serves the purpose of providing information about the app and contacting the Provider. No paid contract is concluded via the website.

§ 3 Conclusion of contract

(1) The contract for the use of the app is concluded with the successful download and installation via the respective app store. The conditions of the platform operator stored there apply additionally.

(2) Contacting us via the form on the website or by email does not constitute a paid contract. It serves exclusively to initiate a possible business relationship or to answer questions.

§ 4 Scope of services and availability

(1) The Provider supplies the app in the version current at the time of download. The exact scope of functions results from the description in the app store and on the website that is valid at the time.

(2) Since the app works offline, a permanent internet connection is not required. No availability of the website or individual functions is guaranteed. The Provider is entitled to perform maintenance and updates that may lead to temporary restrictions.

(3) App updates are provided via the respective app store. The Provider is not obliged to keep individual functions unchanged, insofar as this is reasonable for the user (in particular for security updates or adjustments due to regulatory requirements).

§ 5 Prices and payment

(1) The applicable prices for the app result from the display in the Apple App Store or Google Play Store. Payment is made exclusively via the payment methods stored there by the respective platform operator.

(2) Any in-app purchases or subscriptions are shown separately and are subject to the conditions of the platform operator.

§ 6 User obligations

The user undertakes to:

use the app exclusively within the framework of applicable law;
not deploy malware or circumvent security measures;
not decompile, reverse-engineer or create derivative works of the app, unless this is compulsorily permitted by law (§ 69e UrhG);
not process any data of third parties without their consent;
take care of regular backups of locally stored data themselves.

§ 7 Rights of use

(1) With the download of the app, the user receives a non-exclusive, non-transferable right limited to the duration of the contract to use the app as intended on the end devices supported by the app store.

(2) All rights to the app, in particular copyrights, remain with the Provider or its licensors.

§ 8 Warranty

(1) The statutory warranty provisions of German law apply.

(2) For consumer contracts on digital products, §§ 327 et seq. BGB apply additionally. The Provider provides updates during the update obligation period (§ 327f BGB) that are necessary to maintain conformity with the contract.

(3) The warranty does not cover defects that are due to improper use, modification by the user or incompatibilities with unsupported hardware/software.

§ 9 Liability

(1) The Provider is liable without limitation for intent and gross negligence as well as under the provisions of the Product Liability Act. For slight negligence, the Provider is only liable in the event of injury to life, body or health or in the event of a breach of essential contractual obligations ("cardinal obligations").

(2) In the event of a breach of essential contractual obligations through slight negligence, liability is limited to the foreseeable damage typical for the contract.

(3) Any further liability is excluded. In particular, the Provider is not liable for data loss insofar as the damage is based on the user's failure to make appropriate backups.

(4) Liability for indirect damages, lost profits or consequential damages is excluded within the legally permissible scope.

§ 10 Data protection

The Provider processes personal data in accordance with the requirements of the GDPR and BDSG. Details can be found in the Privacy Policy.

§ 11 Right of withdrawal for consumers

Withdrawal notice — Consumers have a 14-day right of withdrawal when purchasing digital products under §§ 355, 356 BGB. The right of withdrawal expires prematurely if the contract execution has begun with the express consent of the consumer and the consumer has confirmed his knowledge that he loses his right of withdrawal through this consent (§ 356 (5) BGB).

Since the app is purchased via the Apple App Store or Google Play Store, the respective platform operator is responsible for exercising the withdrawal. For questions regarding the withdrawal of an app use, please contact Apple or Google directly.

§ 12 Term and termination

(1) The contract for the use of the app is concluded for an indefinite period. It can be terminated by the user at any time by uninstalling the app.

(2) For paid subscriptions, the cancellation rules of the respective app store apply additionally.

§ 13 Changes to the Terms

The Provider reserves the right to change these Terms with effect for the future, insofar as this is necessary for valid reasons (e.g. change in legal situation, expansion of the scope of services). Changes will be communicated to the user in good time before they take effect in an appropriate manner. If the user does not object to the changes within six weeks, they shall be deemed accepted, provided that the meaning of the silence has been pointed out.

§ 14 Final provisions

(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law applies only insofar as the protection granted is not withdrawn by mandatory provisions of the law of the state in which the consumer has his habitual residence.

(2) Place of performance and exclusive place of jurisdiction for merchants, legal entities under public law and special funds under public law is Dresden, Germany.

(3) Should individual provisions of these Terms be or become invalid, this shall not affect the validity of the remaining provisions.

(4) The European Commission provides a platform for online dispute resolution: ec.europa.eu/consumers/odr. The Provider is not willing or obliged to participate in dispute resolution proceedings before a consumer arbitration board.
