Privacy Policy

TailDose is made by Verntro Labs, LLC ("Verntro Labs", "we", "us"), the party responsible for the data described here. TailDose is built to be private by default. This policy explains exactly what data the app handles, where it lives, and the choices you have.

Data that stays on your device

Everything you enter to track your pets — pet profiles and photos, medications, schedules, dose history, and notes — is stored on your device. If you're signed in to iCloud, iOS also syncs this data to your own private iCloud account using Apple's CloudKit so your devices stay in sync. That iCloud copy is controlled by your Apple account; Verntro Labs cannot access it.

No account is required to use TailDose, and until you sign in for caregiver sharing, none of your data is ever sent to our servers.

Data we store if you use caregiver sharing

Caregiver sharing (inviting family or a sitter to help care for a pet) is optional and requires signing in with Apple. If you use it, we store the following on our server (hosted by Supabase) so your caregivers can see and update the shared pet:

• Account information: a random account identifier, the email address provided through Sign in with Apple (which may be Apple's private relay address if you choose to hide your email), and the display name shown to caregivers (taken from Sign in with Apple the first time you sign in, and editable in Settings → Your name). We also keep a Sign in with Apple token that Apple issues to TailDose when you sign in. It is used for one purpose only: when you delete your account, we send it back to Apple to revoke TailDose's Sign in with Apple access to your Apple ID. It is never shown to anyone or used for anything else, and it is deleted once Apple confirms the revocation (or within a day if Apple can't be reached).
• Shared pet profile: for each pet you share (and only those pets) — its name, species, photo, breed, sex, whether it is spayed or neutered, its birthday and "gotcha" date, and its microchip number, where you have entered them.
• Medications and dose history: each medication's name, dosage, type, schedule and start/end dates, supply and refill settings, and every dose record — when it was due, when it was logged, whether it was given, skipped or missed, any note you added, and which caregiver logged it.
• Health records: weight entries and vaccination records for the shared pet, including dates, clinic, notes, and who recorded them.
• Sharing records: invite links you create, the list of caregivers who joined, and the permission level you gave each caregiver (log doses only, or also edit medications).
• Device registrations: for each device where you are signed in — whether or not you have shared a pet yet — the push token Apple issues to TailDose on that device, a random identifier for that installation of the app, and the device's time zone, so the device can be told to update when a pet shared with you changes and a notification can give a dose time in your own local time. A device's registration is removed when you sign out on it or delete your account.

Pets you do not share are never uploaded to our server. Scanned documents and photos you save in the Documents tab always stay on your device and in your own iCloud — they are never uploaded to our server, even for a shared pet.

What we don't do

• We do not sell, rent, or share your personal data with third parties for their own purposes.
• We do not use your data for advertising, and the app contains no third-party ad or analytics trackers.
• We do not track you across other companies' apps or websites.
• We do not respond to browser “Do Not Track” signals, because we do not track users in the first place.

Information Apple provides to us

As the app's developer, Apple makes limited aggregated and anonymized reporting available to us through App Store Connect. This is the only information about your use of the app that reaches us, and we want to be plain about it. It may include:

• Sales and download reports — aggregate counts of downloads and purchases by territory and date. These do not identify individual users.
• Aggregate app analytics — statistics such as impressions, downloads, sessions and retention. Apple provides these only in aggregated, anonymized form, and only for users who have consented to share analytics with developers in iOS Settings.
• Crash and diagnostic reports — shared with us only if you have opted in to "Share With App Developers" under iOS Settings → Privacy & Security → Analytics & Improvements. These describe technical conditions such as where the app stopped working. They do not identify you and they do not contain your pets' records, medications, or dose history.

We use this solely to understand overall usage and to fix bugs. We cannot use it to identify you, and we do not attempt to. You can stop sharing analytics and crash data at any time in iOS Settings.

Purchases

TailDose Pro subscriptions and purchases are processed entirely by Apple through the App Store. We never see or store your payment information.

Notifications

Dose reminders are local notifications scheduled on your device. They are not sent through our servers.

If you use caregiver sharing, our server sends a silent signal through the Apple Push Notification service to the other devices on a shared pet when something about it changes, so TailDose there can update in the background. The signal is never displayed and contains no pet, medication or personal information — only that something changed.

One notification is different: if you own a shared pet, we notify you when a caregiver gives or skips one of its doses — for example “Rocky's Apoquel — Greg gave the 8:00 AM dose”. To be readable it names the pet, the medication and the caregiver, so that text passes through Apple's push service and can appear on your lock screen. You can turn it off in Settings → Caregiver dose alerts; that choice is kept with your account on our server, because the notification is sent from there. Caregivers are never notified about doses you log yourself.

Service providers

• Apple — iCloud/CloudKit sync of your on-device data, Sign in with Apple (including revoking it when you delete your account), the Apple Push Notification service, and App Store purchases, under Apple's own privacy terms.
• Supabase — hosting for the caregiver-sharing service described above, in data centers in the United States. Data is encrypted in transit and at rest and is processed only to provide the sharing feature.

Data retention and deletion

Shared data remains on our server only while you keep a sharing account. You can delete everything at any time, directly in the app:

• Settings → Delete account permanently deletes your sharing account and all data stored on our server for pets you own, along with your device registrations and notification settings, immediately (or as soon as your device next connects to the internet, if you were offline when you tapped it). Your own pets remain on your device. If you recorded doses, weights or vaccinations for a pet that someone else owns, those entries stay in that pet’s history so its record remains complete, but your name is removed from them. Deleting your account also revokes TailDose's Sign in with Apple access to your Apple ID, as if you had stopped using Sign in with Apple with TailDose in your Apple Account settings. If we don't hold a token for your account (for example, if you haven't signed in since this was added), there is nothing for us to revoke, and you can stop using Sign in with Apple with TailDose yourself in your Apple Account settings.
• Settings → Reset all data additionally erases everything on your device and in your iCloud.
• Stopping the sharing of a pet removes that pet's data from our server.
• When a medication or dose is deleted from a shared pet, a short deletion marker stays on the server so every caregiver’s device removes it too; it is removed with the pet when sharing stops or the account is deleted.

Security

Server data is protected with row-level security so each person can only access pets they own or were invited to, and all connections use encryption in transit (TLS).

Children

TailDose is not directed at children under 13, and we do not knowingly collect personal information from children.

Changes to this policy

If we make material changes, we'll update this page and the effective date above.
