Terms of Service

The short version

• Astrea describes your own data against your own baseline. It is not a medical device and it does not diagnose anything. If something about your health worries you, talk to a doctor.
• Astrea Pro is one purchase. Nothing renews and nothing lapses. Apple sells it, so refunds go through Apple.
• Your health data stays on your iPhone. The privacy policy is the detail.
• We are two people in Dresden. Where something goes wrong that is genuinely ours, we answer for it. The section on liability says how far that goes.

Who these terms are with

These terms are the agreement between you and amazeing GmbH, Schützenplatz 10, 01067 Dresden, Germany, registered at Amtsgericht Dresden under HRB 41927. They cover the Astrea iPhone app and this website, astrea.fit. Full company details are on the imprint page.

By installing the app or using this site, you accept them. If you do not, the app is free to delete and this site is free to close.

If you download Astrea from the App Store, Apple's own Media Services terms apply to that transaction alongside these.

What Astrea is, and what it is not

Astrea reads heart rate variability, sleep, training load and related measurements from Apple Health and compares them with your own recent baseline. It shows you what changed and, where it can, why. That is the whole of what it claims to do.

Astrea is not a medical device. It does not diagnose, treat, cure or prevent any condition, and nothing it shows you is medical advice. A score describes your own measurements. It is not a verdict on your health. If you feel unwell, if a reading worries you, or if you are deciding anything about medication, pregnancy, an injury or a diagnosis, talk to a doctor or another qualified professional. Do not delay doing that because of something Astrea said, and do not ignore what they tell you because Astrea says otherwise.

The measurements themselves come from Apple Health and from the sensors in your devices. Their accuracy is Apple's and your device's, not ours. Sleep staging, heart rate variability and VO2 Max are all estimates, and Astrea's readings are only ever as good as what it is given.

The articles on this site are general information, written carefully and with sources named. They are not advice about you.

Using the app

We grant you a personal, non-exclusive, non-transferable licence to install and use Astrea on devices you own or control, for your own use. You do not buy the software; you buy the right to use it. Everything in the app and on this site — the code, the design, the name, the wordmark, the writing — belongs to us or is licensed to us.

The things you agree not to do are short, and they are the ones that would actually harm someone:

• Copy, redistribute, sell or sublicense the app, or reverse engineer it beyond what § 69e of the German Copyright Act and Article 6 of Directive 2009/24/EC allow you to do anyway.
• Remove or obscure copyright and ownership notices.
• Use the app or this site in a way that breaks the law where you are.
• Interfere with the app's operation, or attempt to obtain a paid feature without paying for it.

Astrea has no accounts, no user profiles and nothing you can publish to other people, so there is no content moderation clause here, and no clause about spam or harassment. There is nowhere in the app to send anyone anything.

Buying Astrea Pro

One purchase, once. Astrea Pro is a non-consumable in-app purchase. It does not renew, does not lapse, and there is no billing period. What you pay is what it costs.

What it unlocks. Today is free and whole. Pro is your history: the Strain, Sleep and Fitness segments of Trends, and opening a past day in the Journal in full. Trends' Recovery segment is free, and on every day your own logged entries and your step count stay free. We do not blur, obscure or padlock a number that is yours; a locked screen shows what it holds and example figures that were never yours.

Apple is the seller. Apple takes the payment, issues the receipt and handles refunds. If you want a refund, request it from Apple, through reportaproblem.apple.com; we cannot issue one and cannot see your payment details. Your statutory rights as a consumer in your country are not affected by anything here. Because the purchase is digital content delivered immediately, the EU right of withdrawal ends once delivery has begun with your agreement, which is the consent Apple takes at the moment of purchase.

Restore works. A new iPhone, a reinstall, a second device on the same Apple Account: Restore Purchases in Profile brings the entitlement back. You do not pay twice.

Prices change; yours does not. We may change the price of Astrea Pro for new buyers. A purchase already made is unaffected. Founding Member pricing, if you took it, is the price you paid, permanently.

Your data

Your health data is read from Apple Health, scored on your iPhone and stays there. We have no account system, no server and no copy of it. The privacy policy sets out exactly what the app reads, what it writes back to Apple Health, and the one thing that does leave your device, which is your purchase.

You control the app's access in Health → Sharing → Apps, and deleting the app removes everything it kept on your iPhone.

This website and the blog

The articles here are ours, and the sources they cite belong to whoever wrote them. You are welcome to quote a passage with a link back. You may not republish an article whole.

Where we link to another site, we are pointing at it. We do not vouch for what it says, and we do not control what changes there after we link.

Joining the Founding Member list means we will write to you when Astrea is ready. It is not a purchase and it holds nothing for you. You can unsubscribe from any email we send.

Availability and changes

Astrea is software under active development. Features arrive, and occasionally one changes shape or goes away. We will not remove something you paid for while your purchase stands. We do not promise that the app or this site is available without interruption, or that it is free of every defect, and we do not promise support for versions of iOS Apple no longer supports.

Updates arrive through the App Store under your own update settings. Astrea installs nothing on its own.

We may amend these terms. When we do, this page changes and the date at the top moves. An amendment applies from the day it is published; if it materially disadvantages you and you do not accept it, your remedy is to stop using the app, and your existing purchase rights are unaffected.

Our liability

We are liable without limit for injury to life, body or health, for damage caused intentionally or by gross negligence, under the German Product Liability Act, and wherever we have given a guarantee.

For ordinary negligence, we are liable only where we breach an obligation that is essential to this agreement — one you must be able to rely on for the agreement to work at all — and then only for damage of a kind that was foreseeable and typical for an agreement like this one. Beyond that, we are not liable.

This section does not limit any liability that German law does not allow to be limited, and it does not affect your statutory rights as a consumer.

Ending these terms

You can end this agreement at any time by deleting the app. We may end it if you breach these terms in a way that is serious and, where the breach can be fixed, is not fixed after we ask. Ending it ends your licence to use the app. Where a purchase has already been made and the breach is not the reason for it, the purchase is unaffected.

Apple

If you use Astrea on an iPhone or an Apple Watch, this section applies, because Apple's own agreement with us requires it.

These terms are between you and amazeing GmbH only, not with Apple Inc. Apple is not responsible for Astrea or its contents, and has no obligation to provide any maintenance or support for it. If Astrea fails to conform to a warranty that applies to it, you may tell Apple, and Apple will refund the purchase price; beyond that refund, Apple has no warranty obligation, and any other claim, loss, liability, damage, cost or expense arising from a failure to conform is our responsibility.

Apple is not responsible for handling any claim you or a third party make about Astrea, including product liability claims, claims that Astrea fails to meet a legal or regulatory requirement, and claims under consumer protection law. Apple is not responsible for investigating, defending or settling a third-party claim that Astrea infringes intellectual property rights.

You confirm that you are not in a country subject to a US Government embargo or designated by the US Government as supporting terrorism, and that you are not on any US Government list of prohibited or restricted parties.

Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

Governing law and disputes

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods.

If you are a consumer resident in the European Union, this choice of law does not take away the protection of the mandatory consumer law of the country you live in, and you may bring a claim in the courts there. Where you are a business, a legal person under public law or a public special fund, the place of jurisdiction is Dresden.

The European Commission runs an online dispute resolution platform at ec.europa.eu/consumers/odr. We are not obliged to take part in dispute resolution before a consumer arbitration board, and we do not.

The rest

If a clause here turns out to be void or unenforceable, the rest stands, and the clause is read down to what the law does allow.

Not enforcing something once does not waive it. You may not transfer this agreement to someone else; we may transfer it if the company is sold or restructured, and your rights stay as they are.

Questions about any of this go to info@astrea.fit, and one of us will answer.
