This privacy policy applies to all personal data processed by us through the MetriWell app, and to all personal data processed by companies commissioned by us (processors).
Personal data refers to information within the meaning of Art. 4 No. 1 GDPR, such as a person's name, email address, and postal address. By processing your personal data, we are able to offer and bill for our services and products. The scope of this privacy policy includes:
- this MetriWell app
- email communication
In this privacy policy, We provide you with transparent information about the legal principles and regulations that allow us to process personal data. We only process your data if at least one of the following conditions is met:
Consent (Art. 6 1 lit. a GDPR): You have given us your consent to process data for a specific purpose, such as entering your data in a contact form.
- Contract (Art. 6 1 lit. b GDPR): We process your data to fulfill a contract or pre-contractual obligations with you, for example, because you have purchased or subscribed to the MetriWell app.
- Legal obligation (Art. 6 1 lit. c GDPR): We process your data if we are subject to a legal obligation, e.g., when issuing invoices.
- Legitimate interests (Art. 6 1 lit. f GDPR): In the case of legitimate interests that do not restrict your fundamental rights, we reserve the right to process personal data; This could, for example, be data that is required to operate the MetriWell app securely and economically.
Generally, we only store your personal data for as long as it is absolutely necessary to provide our services. We delete this data as soon as the reason for processing it no longer applies. In some cases, we are legally obligated to retain certain data even after the original purpose no longer applies, for example, for accounting purposes.
If you request that your data be deleted or revoke your consent to data processing, we will delete your data as quickly as possible, unless there is an obligation to retain it.
According to Art. 15 GDPR, you have the right to information about whether we process your data. If so, you have the right to receive a copy of the data and the following information:
1. For what purpose we process the data;
2. The categories of data being processed;
3. Who receives this data and, if the data is transferred to third countries, how security can be guaranteed;
4. How long the data will be stored.
- You have the right to rectification, erasure, or restriction of processing and the right to object to processing.
- You can lodge a complaint with a supervisory authority.
- You have the right to know the origin of your data if we did not collect it from you.
- You must know whether profiling is being carried out.
- According to Art. 18 GDPR, you have the right to restriction of processing, which means that we may still store your data but may no longer use it.
- According to Art. 21 GDPR, you have the right to object, which, if enforced, will result in a change in the processing.
- If the processing of your data is based on Art. 6(1)(e) (public interest, exercise of official authority) or Art. 6(1)(f) (legitimate interest), you can object to the processing. We will then check as quickly as possible whether we can legally comply with this objection.
- If data is used for direct marketing purposes, you can object to this type of data processing at any time. We may no longer use your data for direct marketing purposes after that.
- According to Art. 22 GDPR, you have the right not to be subjected to a decision based solely on automated processing (e.g., profiling).
- According to Art. 77 GDPR, you have the right to lodge a complaint. This means you can lodge a complaint with a data protection supervisory authority of your choice at any time if you believe that our processing of your personal data violates the GDPR.
If you use external links offered by the MetriWell app, this privacy policy does not apply to these links. When we provide links, we endeavor to ensure that they also comply with our data protection and security standards. However, we have no influence on the compliance with data protection and security regulations by other providers. Therefore, please also inform yourself about the privacy policies provided on the websites of the other providers.
We currently provide informative links to the Apple AppStore and the Google AI chatbot Gemini. Information on data protection with these providers can be found in the section "Data Transfer to Third Parties" and on their websites when using their services.
The MetriWell app does not use WebView components, except for displaying this Privacy Policy and the Terms of Use, and therefore does not use cookies.
We only transfer or process data to third parties or in countries outside the EU (third countries) if you consent to this processing, if this is required by law or contract, and in any case only to the extent that this is generally permitted. Your consent is in most cases the most important reason for us to process data in third countries. Processing personal data in third countries such as the USA, where many software manufacturers offer services and have their servers located, may mean that personal data is processed and stored in unexpected ways.
By purchasing the MetriWell app or subscribing to a subscription, you will be redirected to the App Store of Apple Inc., One Apple Park Way, Cupertino, CA 95014, USA, as Apple handles the sale of the app and the processing of subscriptions for us, both legally and financially. We have no influence on restricting Apple's processing or influencing the duration of data storage or use. If you do not want your personal data to be transmitted to Apple, do not purchase the app or subscribe within the MetriWell app. You can obtain more information about how Apple uses your data during and after purchasing metriwell or subscribing to a subscription from Apple.
Additionally, we make use of RevenueCat, which is an infrastructure platform that simplifies and standardizes in-app subscriptions and purchases, allowing us to manage payments and optimize revenue without building our own complex billing systems. When buying or subscribing to the MetriWell App, you will be redirected to RevenueCat, Inc. a Delaware corporation with a place of business at 1032 E Brandon Blvd #3003, Brandon, FL 33511. We have no influence on restricting RevenueCat's processing or influencing the duration of data storage or use. If you do not want your personal data to be transmitted to RevenueCat, do not purchase the app or subscribe within the MetriWell app. You can obtain more information about how RevenueCat uses your data during and after purchasing metriwell or subscribing to a subscription from RevenueCat.
As soon as you start an AI chat or an AI analysis within the MetriWell app, a so-called AI prompt is created. This prompt contains the personal data required for the analysis as an extract from your HealthKit data. This data is transferred to our local webserver and from there to our local LLM server, both operating on our dedicated servers in Germany, currently operating with google/gemma3. This data is anonymous, and we never know who sends it to our server. However, outgoing chat responses are logged by the LLM server. We reserve the right to use this outgoing data to improve our AI training service. As soon as the original data is no longer needed, it is immediately deleted. If you do not want to consent to data transfer to us, do not start an AI chat or an AI analysis!
The MetriWell app has no knowledge of your identity, your bank or contact details, or any other personal data; simply put: MetriWell doesn't know you.
If you allow us to access your Apple HealthKit data, MetriWell will not cache any HealthKit data on your iPhone. But we will cache AI responses, where applicable and meaningful (e.g. responses on your ECG readings, which would not change essentially, even if asking the AI for another summary).
The only information that the MetriWell app regularly requests from Apple and/or RevenueCat and retains in memory for the duration of its operation (from the start to the end of the app) are the details of your purchase or subscription to the MetriWell app, which are retrieved from the Apple App Store and/or RevenueCat. Specifically, these are:
- Purchase ID: a unique string that identifies your purchase/subscription,
- Product ID: a string assigned by Apple for the MetriWell app and the various purchase/subscription options,
- Verification Date: the timestamp that represents the approval of your purchase/subscription,
- Transaction Date: the timestamp that represents the actual purchase/subscription, and
- Status: the status of your purchase/subscription.
The AI prompts created by the MetriWell app are deleted from the app's memory immediately after they are applied and are not permanently saved.
