These Terms of Use (the “Terms”) govern your use of the Hardtack application (the “App”) and this website. By installing, purchasing or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. Purpose and acceptance

Hardtack is a home inventory mobile application designed to work offline. It helps you list your supplies, track expiry dates and estimate how long your stock will last. These Terms form an agreement between you and the publisher of Hardtack. They apply to every version of the App, on both iOS and Android.

2. License to use the App

Subject to your acceptance of these Terms and payment of the purchase price, the publisher grants you a personal, worldwide, non-exclusive, non-transferable and revocable license to install and use the App on devices you own or control, for personal, non-commercial purposes.

You agree not to: (a) copy, modify, distribute, sell or lease all or part of the App; (b) reverse engineer, decompile or disassemble the App, except to the extent permitted by law; (c) circumvent or disable any technical protection or licensing measures; (d) use the App for any unlawful purpose or in breach of these Terms.

3. One-time purchase and store-managed purchases

In version 1.0, Hardtack is offered as a one-time purchase at the price shown on the App Store or Google Play for your region (excluding any applicable taxes). It is a “non-consumable” in-app purchase: once paid, access to the purchased App is yours with no subscription and no recurring charges.

All purchases are made and processed exclusively by the Apple App Store or the Google Play Store, depending on your platform. Pricing, billing, taxation and restoring your purchase (for example on a new device or after reinstalling) are governed by the terms of the relevant store. We neither receive nor store your payment details.

Refunds: refund requests are handled directly by Apple or Google under their respective policies. We are unable to process refunds on our side; please contact the store where the purchase was made.

Future subscription features: an encrypted cloud backup option (“Cloud Backup”) is planned for a later release (v1.1 and beyond). It would be a separate, optional subscription, subject to specific terms presented at the time of subscribing. It does not change the one-time purchase of the App described above, which remains yours for life.

4. Availability and “as is” provision

The App is provided “as is” and “as available”, without warranty of any kind, express or implied, to the extent permitted by applicable law. We do not warrant that the App will be error-free or uninterrupted, or that it will meet all of your requirements. You are responsible for backing up your own data; because Hardtack works offline, your data resides on your device and may be lost if the device is lost, fails or is reset.

5. Disclaimer and limitation of liability

Hardtack is an inventory and organization tool. The estimates it provides (autonomy duration, expiry dates, quantities, values) are indicative and based on the information you enter. They do not constitute medical, nutritional, legal, safety or professional advice, and are no substitute for the judgement of a qualified professional or the guidance of the competent authorities. You remain solely responsible for your decisions and for verifying your supplies and equipment.

To the fullest extent permitted by law, the publisher shall not be liable for any indirect, incidental, special or consequential damages, nor for any loss of data, arising from the use of or inability to use the App. Nothing in these Terms limits or excludes any liability that cannot be limited or excluded under applicable law, in particular for wilful misconduct or gross negligence, nor any rights you have under mandatory consumer-protection provisions.

6. Intellectual property

The App, its code, interface, texts, logos, the “Hardtack” trademark and all of its graphic elements are protected by intellectual property law and remain the exclusive property of the publisher or its licensors. These Terms transfer no ownership rights to you, only the license to use described in section 2. The inventory data you create belongs to you and remains under your control.

7. Governing law and jurisdiction

These Terms are governed by French law and, where applicable, by the law of the European Union. Any dispute relating to their interpretation or performance shall be subject to the competent French courts, without prejudice to the mandatory consumer-protection rules that allow you to bring proceedings before the courts of your place of residence within the European Union. Where applicable, you may also use the European online dispute resolution platform.

8. Changes to these Terms

We may amend these Terms to reflect changes to the App or to the legal framework. The applicable version is the one published on this page, with its update date. By continuing to use the App after a revised version is published, you accept the amended Terms.
