Oryn

Privacy Policy

Last updated 14 August 2026

Oryn is a personal health app. It only works if you trust it with sensitive information, so this policy describes what is actually stored, where it goes, and how long it stays — in plain language, matching what the software does.

Oryn is built and operated by an independent developer ("we", "us"). This policy covers the Oryn iPhone app and the Oryn service, which is reachable at oryn.ink and oryn.azimboev.uz — the same service under either name.

The short version

What we collect

Account information

Depending on how you sign in, we store some combination of: an email address, a username, a display name, a password verifier (hashed with Argon2 — never the password itself), and an opaque account identifier provided by Apple or Google when you use Sign in with Apple or Google Sign-In. We also store your time zone, so a "day" in the app matches your day. Name and email are optional; Oryn works without them.

Health data

Oryn reads a deliberately narrow set of signals — only what the product actually uses:

SignalWhere it can come from
Sleep durationApple Health, Google Health
StepsApple Health, Google Health
Resting heart rateApple Health, Google Health
Heart rate variabilityApple Health, Google Health

Alongside each measurement we keep the context needed to interpret it honestly: which source reported it, the time range it covers, and — when two sources disagree — a record of how the merged value was decided.

Connection and operational records

To keep syncing reliable we store records of your connected devices and integrations, the status and timing of sync runs, and de-duplication receipts that stop the same upload being counted twice. We keep a privacy audit log of sensitive actions such as export and deletion requests; entries in that log identify you only by a one-way hash, never by your name, email, or account identifier.

We also record what goes wrong: failed syncs, records a source sent that we could not interpret, and background work that gave up. These records hold identifiers and error codes so we can find the problem — never a measurement. Separately, and unlike the privacy audit log above, we keep an operations log of everything our own staff do in the support tools, which does name the account that was looked at. That is the deliberate trade described under Who else sees your data.

What we do not collect

We do not collect advertising identifiers, location history, contacts, browsing behaviour, or any health category beyond the four listed above. This website sets no cookies and loads no external fonts, scripts, or trackers.

How your sources are connected

Apple Health

Apple Health data never leaves your iPhone without your explicit permission, granted per data type through Apple's own permission screen. You choose which signals Oryn may read, and you can change or revoke that at any time in the iOS Health app. Data obtained through Apple HealthKit is used solely to provide the features described here. It is never used for advertising or marketing, never sold, and never shared with third parties. It is not used for any purpose other than your own health insights.

Google Health

Connecting Google Health is optional; Oryn works with Apple Health alone. If you do connect it, Oryn requests read-only access to exactly three scopes, each tied to a specific feature:

ScopePurpose
googlehealth.sleep.readonlyRead sleep duration for your daily view and sleep baseline.
googlehealth.activity_and_fitness.readonlyRead daily step counts, and de-duplicate movement counted by more than one device.
googlehealth.health_metrics_and_measurements.readonlyRead resting heart rate and heart rate variability for your recovery baseline.

We never request write access, and Oryn cannot modify anything in your Google account. Access tokens are encrypted before they are stored, and you can disconnect at any time — from inside Oryn, or from your Google Account permissions page. Disconnecting stops future syncing; data already synced is removed when you delete your account or the integration.

Limited Use. Oryn's use and transfer of information received from Google APIs to any other app adheres to the Google API Services User Data Policy, including the Limited Use requirements. Specifically, data obtained through these scopes is used only to provide and improve the features described in this policy; it is never transferred to others except as required to operate the Service, to comply with applicable law, or as part of a data export you request; it is never used for advertising; and no human reads it except with your explicit consent, for security purposes, or where required by law.

How we use it

Your data is used to operate the product you asked for and nothing else: to merge signals across sources, build your daily view and personal baselines, explain how a merged value was reached, keep syncing working, and secure your account. We do not profile you for advertising, and we do not use your health data to train machine learning models.

How it is protected

No system is perfectly secure, and we will not pretend otherwise. We design to limit what an incident could expose.

How long it is kept

DataRetention
Account and health dataUntil you delete your account
Data export archives24 hours, then automatically revoked and erased
Privacy audit log (hashed)90 days
Operations log of staff access1 year; the account identifier is removed as soon as the account is deleted
Error recordsDeleted with your account; resolved ones are cleared after 90 days
Live data after a deletion requestRemoved within 24 hours
Encrypted backups after deletionExpire on their own schedule within 30 days

Your choices

Who else sees your data

We do not sell, rent, or trade your data, and we do not share health data with advertisers, data brokers, or analytics providers. Your data is processed by us and by the infrastructure providers that host the servers and the database on our behalf, under their standard confidentiality obligations. Apple and Google act as the sources you choose to connect and receive only what is needed to authenticate you and read the signals you approved. We may disclose information if we are legally compelled to, and we will not do so silently unless the law forbids telling you.

Our own staff

Oryn has internal support tools, and through them our staff can see your account, your connected sources, the errors your account has hit, and your health measurements themselves — the same values the app shows you, and the original records your phone or Google uploaded.

We would rather not have that access, and we thought about withholding it. But when someone writes to say "my sleep has been missing since Tuesday", the honest answer requires looking at what actually arrived and what the app did with it. A support tool that could not see the data could not answer the question.

So the access exists, and we constrain it instead of pretending it does not:

What the tools cannot do is quietly change your measurements. Merged results and personal baselines are protected against modification by the database itself; the only way to correct a wrong value is to run the calculation again over the original records, and the original records are what your source sent us.

Staff can also block an account, which stops it being used but deletes nothing and can be undone, and can start the same deletion you can start yourself — which cannot be undone. If we block your account, we will tell you why.

Children

Oryn is not intended for anyone under 16, and we do not knowingly collect data from children. If you believe a child has created an account, write to privacy@oryn.ink and we will delete it.

Changes

If this policy changes in a way that materially affects you, we will update the date at the top and notify you in the app before the change takes effect. Continuing to use Oryn after that means the updated policy applies.
