In the E4L GEM app, we store your sign-in, settings, and some of your data on your device so the app works offline. Deleting the app removes it from your device.
We do not retain data for any longer than is necessary for the purposes described in this Policy. We generally retain data according to the guidelines below.

We process personal information for the following business and commercial purposes:
When you use the E4L GEM app and the GEM wearable, we also collect:
We use health information, including data from your GEM or other wearable only to provide and improve E4L's wellness features for you. We do not sell your information. We do not use it for advertising, marketing, or data mining. We share it only as described under "How We Disclose Your Information" below, mainly with the service providers who help us run the app, and with your practitioner only if you choose to share with them. You can disconnect Apple Health or Health Connect, or turn off your GEM, at any time. Both options stop new data from being collected. To delete the data we already hold, use "Delete my data".
We use technical and organizational measures to protect your information, including:
No system is completely secure, but we work to protect your information and review our safeguards as our services change.
The Coach uses artificial intelligence to write its replies. To answer you, it uses the following information when it has been provided: personal information like age, sex, height, and weight; your messages, intake answers, and scan results; notes it has saved from earlier conversations; wearable data; and any other form of health data you may provide. We use OpenAI to generate the Coach's replies. OpenAI processes your information only to provide this service to us, does not use it to train its models, and does not keep this data. We keep Coach conversations to review and improve the Coach. The Coach saves notes about you unless you turn this off under Profile › Your data. Turning it off stops the Coach using or saving notes about you. It does not delete notes already saved; to delete those, use "Delete my data".
If you dictate a message, the speech recognition built into your phone or browser (provided by its maker, such as Apple or Google) turns your speech into text. We receive only the text you send.
If you scan a friend, you can give us their name and mobile number, and we collect their voice recording and tongue photo. You must have their permission first. We use their number only so you can text them their result from your own phone. Their result is available through a private link for 7 days. From that page they can add it to their own E4L account, or delete the scan, its recordings, and the link. If they do neither, we delete the scan and its recordings after the link expires.
Under Profile › Your data, you can stop the AI Health Coach using or saving notes about you. You can also delete your data (scans, GEM data, Apple Health and Health Connect data, tongue and voice results, Coach chats and notes, and scans of friends) and keep your account, or delete your account and all its data, with exceptions discussed above under "How Long We Keep Your Data." You can turn notifications on or off under Profile › Notifications. You can change Apple Health or Health Connect permissions in those apps' settings. You can also ask us to access, correct, or delete your information through our Make a Privacy Request page.
The E4L GEM app is not intended for anyone under 18, and we do not knowingly collect information from them.
We do not sell personal information collected through the E4L GEM app, and we never share health information for advertising or marketing. Some information collected on our website is shared with advertising partners, which some US state laws treat as a "sale"; our US State Privacy Notice explains this and how to opt out. We disclose personal information to:
We and our service providers store and process information in the United Kingdom, Canada, and the United States. If you live outside these countries, your information is transferred to them.

If you live in the UK, data protection laws such as UK GDPR give you the rights below.
