Terms of Use

1. Who these terms are with

These Terms of Use (the “Terms”) form an agreement between you and Kristmann Technologies, sole proprietor Claudius Kristmann, Michael-Ludwig-Rohrer-Straße 1/1, 76437 Rastatt, Germany (“we”, “us”), the provider of the Habit Tracker Grid iPhone app (the “App”). The full provider identification is in the legal notice. By downloading, installing or using the App you agree to these Terms. If you do not agree, please do not use the App.

2. What the App does

Habit Tracker Grid is an iPhone app that shows habits as a contribution grid: every day you complete fills a cell, gaps stay visible, and a whole month can be taken in at a glance. Habits can have a goal with a unit and a step size, and the App can remind you per habit at a time you choose. Your data lives on your device and in your iCloud.

3. Licence to use the App

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable and revocable right to use the App on Apple devices that you own or control — in line with the Apple Media Services Terms and Apple's standard end user licence agreement for licensed applications. You may not copy, modify, reverse-engineer, resell or distribute the App except where the law expressly permits it.

4. Requirements

The App requires an iPhone running an iOS version supported by the App. Syncing requires an active iCloud account; without iCloud, the data stays local on the device. You are responsible for making sure your device meets these requirements.

5. Free use and Premium subscription

• The App is free to use: up to two habits are available permanently and without a time limit — with the full contribution grid, countable goals, reminders, the JSON backup and all six languages. There is no user account and there are no ads.
• Premium lifts the limit of two habits and additionally unlocks six themes with a colour you pick yourself, your own background image and statistics.
• Premium is offered as a recurring subscription: €4.99 per month or €14.99 per year. The yearly plan starts with 7 days free. The prices shown in the App Store at the time of purchase are the ones that apply.
• Billing is handled entirely by Apple through your Apple ID. The amount is charged to your Apple account when you confirm the purchase.
• Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. The charge for the renewal is made within 24 hours before the period ends.
• You can manage or cancel your subscription and turn off automatic renewal at any time in your App Store account settings (Settings → your name → Subscriptions). Deleting the App does not cancel a subscription.
• Refunds are handled by Apple under its own policies. We do not process payments and therefore cannot issue refunds ourselves.

6. Acceptable use

You agree to use the App lawfully and in particular not to:

• circumvent technical limitations, security measures or the subscription check;
• use the App for unlawful, harmful or fraudulent purposes;
• infringe the rights of others;
• interfere with the operation or integrity of the App.

7. Your data

The habits, ticked-off days, settings and backups you create with the App belong to you. We claim no ownership of them and, because the App stores your data on your device and in your iCloud, we have no access to it. You are responsible for backing up your own data — the App provides a full JSON backup and restore for exactly that.

8. Our intellectual property

The App itself — its software, design, name and underlying technology — belongs to us or our licensors and is protected by copyright and trade mark law. These Terms grant you no rights in it, apart from the limited licence in Section 3.

9. Third-party services

The App uses Apple frameworks and services (including StoreKit and iCloud), RevenueCat to check subscription status, and Sentry for anonymous crash and performance data. Their own terms and privacy notices apply to those services in addition to these Terms. What data is processed is set out in the privacy policy. We accept no responsibility for third-party services we do not control.

10. Warranty

To the extent permitted by law, the App is provided “as is” and “as available”. We do not warrant that it will run without interruption or error. Habit Tracker Grid is a tool for organising yourself and is not a medical application; it makes no diagnosis, gives no health advice and replaces no medical or therapeutic consultation. Mandatory statutory warranty rights, in particular those of consumers, remain unaffected.

11. Liability

We are liable without limitation for damage arising from injury to life, body or health, in cases of intent and gross negligence, and in all cases of mandatory statutory liability, including liability under the German Product Liability Act. In cases of simple negligence we are liable only for the breach of an essential contractual obligation (Kardinalpflicht), and then limited to the foreseeable damage typical of this kind of contract. Liability is otherwise excluded, in particular for the loss of data where that loss could have been avoided by proper and regular backups — for example using the App's backup feature.

12. Term and termination

You may stop using the App at any time and delete it. We may suspend or terminate access if you materially breach these Terms. Provisions that by their nature should survive — such as those on intellectual property, warranty and liability — remain in force after termination.

13. Governing law

These Terms are governed by the law of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection of mandatory provisions of the law of the country in which you are habitually resident.

14. Consumer dispute resolution

We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.

15. Changes to these Terms

We adapt these Terms when the App or the legal situation changes. The current version is always on this page; the date above states when it was last updated. If you keep using the App after a change takes effect, that counts as acceptance of the revised version.
