Privacy Policy

Last updated — September 29, 2026

Dosify Me is a peptide reference, reconstitution math and reminder app for adults 21 and over. This policy explains, plainly, what the app collects, what the dosifyme.com website collects, what stays on your device, what happens if you choose to sync between devices, and who else can see it.

The short version. Your schedules, dose log and vials stay on your device. The only way they leave it is if you choose to create an optional account: then your data is stored in that account on Google Firebase, linked to your email, so you can sign in on your other devices and at dosifyme.com. You can delete your account and everything in it from inside the app at any time.

Your name and email

Some versions of the Android app ask for your name and email when you first open them; the iPhone app and newer Android versions do not. We store them on our servers (Google Cloud Firestore) and use them to send you updates and promotions about the app.

When you submit them, the app also looks up your approximate area — city, region and country — from your internet (IP) address, using the ipapi.co lookup service, and stores that area alongside your name and email. It is never GPS and never your street address.

Your name and email are kept separately from your dosing data. The one exception is an account you choose to create (see “Accounts and sync (optional)”): the email you sign in with is, by design, linked to that account's data.

The mailing list on this website

Separately from the app, dosifyme.com has a signup form for occasional updates — when new compound cards are added to the reference, when reconstitution data is revised, or when the app updates. Reference material only: no promotions, no advice, and we never email you about which compounds you track, because we do not know.

What we store when you sign up:

Your email address
The date and time you signed up
A random confirmation token
The date you confirmed, and the date you unsubscribed, if either happens
Which site the signup came from (always dosifyme.com today)
Your country, as reported by our hosting provider

What we deliberately do not store: your IP address, your browser or device, the page you arrived from, or anything at all about your dosing.

Nothing is sent to you until you confirm. A signup is recorded as unconfirmed, and an unconfirmed address is not mailed. You can unsubscribe from any email, and we will stop.

Where it lives: the list is stored in a Cloudflare D1 database that we control. It is not shared with an email marketing company, an advertiser, or a data broker, and it is never sold.

Deleting it: email [email protected] and we will remove your address. We also intend to delete unconfirmed signups after 30 days, since an unconfirmed address is someone who never asked to be on the list.

Usage and crash data

Dosify Me uses Google Firebase Analytics and Crashlytics to see how the app is used and to catch bugs. That covers which screens you open, in-app events like submitting the signup form, crash reports and error details, and what Firebase collects automatically — a random app instance ID, your device model, OS and app version, country, and session timing. Google processes this for us.

Analytics records which kind of screen you opened, not which compound was on it. It is not connected to your name and email, and it is not connected to your synced data.

Your dosing data, and where it lives

The app keeps this information about your own use:

Which peptides you've added to "My Peptides"
Your dose schedules — which peptide, frequency, time of day, chosen dose amount and unit, and whether the schedule is active
Your dose log — timestamps of doses you've marked "taken" or "skipped"
Your vials — vial size, water amount and reconstitution choices per peptide, and your vial inventory
Your weight log, if you use it
Your app preferences — preferred dose unit (mg/mcg/both), syringe size, reconstitution syringe size, temperature unit, background color, and language
Whether you've acknowledged the app's informational disclaimer and confirmed you are 21 or older

Where that information is stored depends on whether you use an account. You choose; the app never copies your data anywhere unless you create an account or sign in to one.

Without an account (the default)

Everything above is stored only in your device's built-in storage. It is not sent to us or to anyone else. We never receive your schedules, doses, vials or history, and we don't know which peptides you track.

With an account (optional)

If you create an account or sign in to one, your data is stored in that account in Google Firebase Cloud Firestore so it can sync to your other signed-in devices. What is stored, how it is protected and how to delete it are described under “Accounts and sync (optional)”. Nothing is copied to the account until you create it or sign in.

Apple Watch

The Apple Watch app does not use any cloud service. It talks directly to your paired iPhone over Apple's watch connection, and only shows what the iPhone sends it.

Using Dosify Me on a computer

The web version at dosifyme.com is for people with an account: you sign in with its email and password. Accounts are created in the app.

Sessions end on their own. A computer is signed out automatically after 30 days without use.
You can sign a computer out from your phone, at any time, from the list of signed-in devices in the app (Settings › Account) — useful if you used a shared or work computer.
When a session ends — you sign out, you sign it out remotely, or it expires — that browser can no longer reach your synced data, and the web app clears its local copy the next time the page is opened on that computer.

If you use a computer other people share, sign out when you're done rather than waiting for the session to expire.

How long account data is kept

Signing a device out: that device stops syncing and keeps its own local copy. The account and its data stay available to your other signed-in devices.
Deleting your account (Settings › Account › Delete account): your login, account record, device list and all data stored in the account are deleted right away. Each device keeps its own local copy until you remove it (see our Data Deletion page).
Backups: we do not keep separate backup copies of account data. Once it is deleted from the database, we cannot restore it.

Accounts and sync (optional)

You never need an account to use Dosify Me. If you create one in the app (Settings › Account), your data follows you when you sign in on another phone, a tablet or dosifyme.com. This is how accounts work:

What we store for an account: your email address and a password. The password is handled by Google Firebase Authentication, which stores it in hashed form; we never see it. The account also gets a random account ID.
Your data in the account: the dosing data listed above — schedules, dose log, vials and vial inventory, weight log, favorites and settings — plus your language, your 21+ and disclaimer acceptance, your free-trial start date, redeemed promo codes and whether you were already asked for a review. It is stored in Google Firebase Cloud Firestore, linked to your email. Only devices signed in to your account can read it through the app; our database rules refuse every other device. It is encrypted in transit and stored encrypted by Google. It is not end-to-end encrypted: Google, as the host, and we, as the operator of the database, technically have the ability to access it. We do not look at individual users' data, we do not use it for analytics or marketing, and we do not sell or share it. We would access it only if needed to keep the service running, to fix a problem you ask us to fix, or if required by law.
Your signed-in devices: to enforce the device limit (two phones, one tablet and one browser at a time) the account keeps, for each signed-in device, its model name (for example “Pixel 8”, or for a browser “Chrome · Mac”), whether it is a phone, tablet or browser, when it signed in and when it was last used, plus a short history of recent device replacements. You can see these devices in Settings › Account.
Your subscription: when you are signed in, our subscription provider RevenueCat identifies your subscription by your random account ID instead of an anonymous ID, so a subscription bought on one device also unlocks your other signed-in devices, including on the other store or on dosifyme.com. RevenueCat therefore holds your purchase history under that account ID. We never give RevenueCat your email, your password or any dosing data. Payments are still made only through Apple or Google.
Emails about your account: Firebase sends one email to confirm your address when you create the account, and a password-reset email only when you ask for one. Signing up for an account does not add you to any mailing list.
Signing out: the device stops syncing and keeps its own copy of your data; the account and its data stay available to your other devices. A signed-out device goes back to an anonymous subscription ID.
Deleting your account: in the app, Settings › Account › Delete account (you confirm with your password). This deletes your login, your account record, the device list and all data stored in the account, right away. Each device keeps its own local copy until you remove it (see the Data Deletion page). Purchase records kept by Apple, Google and RevenueCat for billing and tax purposes are governed by their own retention rules; email [email protected] and we will ask RevenueCat to delete the customer record for your account ID too. If you can no longer sign in, email us from the address on the account.

Reminders

Dose reminders use your device's own local notifications. There's no push service and no token sent anywhere. We ask for notification permission only when you actually set a reminder. Syncing a schedule to another device sets that device's own local reminders; it does not use a push service.

Subscriptions and payments

Subscriptions and free trials are purchased through Apple's App Store or Google Play. Apple or Google handles your payment details; we never see your card. We use RevenueCat to check whether your subscription is active. RevenueCat receives purchase and subscription status tied to a random, anonymous ID — or, if you are signed in to an account, to your random account ID, as described under “Accounts and sync (optional)”. We do not give it your name, email or any dosing data.

Third parties

These companies process data for us, and no others:

Google Firebase handles the app's analytics and crash reporting, stores the name and email you submit, verifies that requests come from the genuine app (Firebase App Check, which relies on Apple's App Attest or DeviceCheck, or Google Play Integrity), and — only if you create an account — handles its sign-in and stores its data as described above.

RevenueCat checks subscription status, as described above.

ipapi.co turns your IP address into an approximate city, region and country when you submit your name and email.

Cloudflare hosts dosifyme.com, including the web version of the app, stores the mailing list in its D1 database, and runs the bot check on the signup form. That bot check (Cloudflare Turnstile) sends your IP address to Cloudflare to verify the submission is not automated; we do not receive or store it.

Apple and Google process subscription payments. They do this under their own privacy policies, as the providers of your account and store.

There's no advertising SDK, the app does not track you across other companies' apps or websites, and we don't share or sell your data to advertisers or data brokers. Links to FDA labeling and journals open in your browser only if you tap “Sources” — the app doesn't fetch them for you.

Where data is processed

We are based in the United States. Google, Cloudflare, RevenueCat and ipapi.co may store and process data on servers in the United States and other countries, which may have different data-protection laws from where you live. If you use Firestore sync, your synced data is stored on Google's servers, which may be outside your country. Where the law requires it, we rely on the transfer safeguards these providers offer, such as standard contractual clauses.

Your rights and choices

Delete your account yourself: in the app, Settings › Account › Delete account.
Delete synced data yourself: in the app, open the linked-devices screen and choose “Delete synced data”. You can also unlink any single device or sign out a computer there.
Delete data on your device: see the Data Deletion page.
Everything else, or if you've lost your devices: email [email protected] and we'll tell you what we hold about you, correct it, or delete it. If you have an account, email us from the address on the account so we can find it. Data stored only on a device never reaches us, so we cannot see or delete it for you.

Depending on where you live you may have further rights under laws such as the GDPR or CCPA, including access, correction, deletion, portability, and objecting to marketing. Your mailing-list entry is covered too: ask and we will delete it, or use the unsubscribe link in any email.

Age requirement

Dosify Me is for adults 21 and over, and the app asks you to confirm your age before use. It is not intended for anyone under 21, and we don't knowingly collect data from children. If you believe someone under 21 has given us their name or email, or synced data to our servers, contact us and we'll delete it.

Changes

If this policy changes, the "Last updated" date above changes with it. If we start collecting materially more, we'll say so in the app, not just here.
