There is no subscription to cancel to keep your Ultrahuman Ring data: “One purchase gives you lifelong access to the ring and your data,” Ultrahuman says, and your history stays with your account. Ultrahuman’s privacy policy, terms and ring FAQs, though, describe no download of ring data, so on an iPhone keep the Apple Health integration on, and ask Ultrahuman for the rest. Programmers can also read their daily metrics through Ultrahuman’s API.

The ring needs no subscription
“Rest assured, there are no recurring subscription fees for accessing your data,” says the Ring AIR FAQ, and the Ring PRO FAQ answers “Is there a subscription fee?” with “No.” The paid extras are PowerPlugs: “Charges apply only to medical-grade experiences or partner-developed solutions,” and they work “without altering or limiting any of the core app functionalities” (Ultrahuman, PowerPlugs). Ultrahuman Max, an optional plan from $9.99 a month or $99.99 a year in the US, bundles the premium PowerPlugs with UltrahumanX cover for accidental damage, loss and theft (Ultrahuman, US store). Ultrahuman does not say what happens to a PowerPlug’s data when you stop paying for it or for Max.
Your data lives with the account
“Your data lives with your Ultrahuman account, not the ring, so your history stays intact when you pair a new ring” (Ultrahuman, Ring PRO FAQ). Ultrahuman’s privacy policy, updated on 13 September 2026, says “You own your data and control our usage of your data.”
On how long it keeps the data, the same policy says: “We keep your information only for as long as necessary to provide you with our Products and Services or as may be required under any applicable law.” It states no period after which an unused account is deleted. Closing the account is different: “If you close your User Account, we have no obligation to retain your data, and we may delete any or all of your data without liability.” To have your data deleted, Ultrahuman asks you to write to support@ultrahuman.com.
Keep a copy yourself
Ultrahuman’s privacy policy, terms and ring FAQs describe no download of ring data. On an iPhone, Ultrahuman writes readings such as “heart rate variability, temperature or energy expenditure” to Apple Health. To turn it on, open the Health app, tap your profile picture, then Apps, Ultrahuman and Turn All Categories On (Ultrahuman Blog).
Apple Health then holds those readings on your phone, and its own export, Export All Health Data from your profile in the Health app, saves them as a file. These are the values the app wrote, not the beat intervals behind them, and Ultrahuman does not say which HRV statistic it writes. Turn the integration on before you stop using the ring: Apple Health keeps only what it receives. How to export your HRV data explains the route and its limits.
If you can run a script, Ultrahuman’s developer documentation describes a second route: a personal API token, created in its developer portal, that reads your own account’s daily metrics, including heart rate, HRV, skin temperature, sleep stages and scores, up to 7 days per request (Ultrahuman, UltraSignal API). It is a programming interface, not a download button, and we could not check without an account how the portal issues tokens.
Ask for a copy
With no download button, a request is the simplest way to a full copy:
- Where: “You can exercise all these rights by raising a request to us at legal@ultrahuman.com.” In the EEA and the UK you can also write to Ultrahuman’s Data Protection Officer, Ametros Group, at dpo@ametrosgroup.com (Ultrahuman Privacy Policy).
- What to ask for: Ultrahuman’s policy lets you “request details of your information collected by us” and “request a portable copy of the information you have provided”. Name the readings: Ultrahuman says the ring records beat intervals “in readings of about 24 s, every 5 to 6 minutes” (Ultrahuman, HRV accuracy). Ask for those readings with their beat intervals, the nightly HRV, heart rate, skin temperature, sleep stages and scores, the dates and a format such as CSV or JSON. Wearable data rights explains why the copy should hold the data, not a summary, and where that argument stops.
- When: Ultrahuman states no deadline. Under the GDPR and the UK GDPR a company must answer within one month, extendable by two more where necessary because of the complexity or number of requests (GDPR Article 12). Californians can ask for what was collected in the previous twelve months, the policy says. Under the GDPR the first copy is free (Article 15(3)); a company may refuse even a first request only exceptionally, if it proves the request was made with an abusive intention (Court of Justice, C-526/24).
A bar chart of response deadlines in calendar days, one bar per place, from 0 to 90 days. EU and EEA (GDPR): 1 month, up to 3 where necessary for complex or numerous requests. United Kingdom (UK GDPR): 1 month, up to 3 where necessary for complex or numerous requests. California (CCPA): 45 days, up to 90 when reasonably necessary, with notice. Brazil (LGPD): 15 days for the complete declaration. South Korea (PIPA): 10 days; may be postponed with a stated reason. Russia (152-FZ): 10 working days, up to 15 with a reasoned notice. Japan (APPI): “Without delay”: no number of days.
The data request letter builder has Ultrahuman’s addresses and puts these points into a letter. Wearable data rights covers reminders and complaints, and Ultrahuman HRV explains the ring’s Sleep HRV.
