Tailbook is a pet care log: every pet’s vaccinations, treatments, medicines, vet visits and weight, with what is due shown first. We do not create accounts, do not ask for your email, and do not ship any analytics or tracking SDK. Your pets, their care, visits, weights and photos stay on your phone. Tailbook never sends them anywhere. They leave the phone only if you share a care record through Android’s share menu, to an app you choose, or save a backup or CSV file where you choose. A backup file and a CSV file are plain files and are not encrypted.
Every due date, every overdue item and the daily reminder are worked out on the phone, so keeping the record never uses the internet. Tailbook keeps your own record and gives no veterinary advice. The app contains no code that can reach a server at all, apart from the advertising SDK described below, which receives nothing from your record.
If that’s all you wanted to know, you’re done. The sections below spell it out in detail.
com.dashfusion.listpet)The following is created and kept locally, in the app’s private storage:
Your pets’ details, their photos and the vet’s name and phone are kept here and nowhere else. They leave the phone only when you act: a care record you share carries the pet’s details and photo and the vet’s name and phone, and a backup you save carries your whole record, photos included. Tailbook never sends them anywhere itself.
The app explicitly opts out of Android cloud backup and device-to-device transfer, so Android never copies your record or your pets’ photos to Google Drive or to another phone. A new phone starts with an empty record unless you restore a backup you saved. The app says so in Settings.
You can delete a weighing, a vet visit, a day a care item was done, a care item, or a pet with everything under it, photo included; remove a pet’s photo; use Settings → Delete everything; or uninstall the app — Android removes the local data with it. Delete everything keeps only your currency and your settings. We have no servers and no cloud storage. We cannot see your record and we cannot recover it if you lose your device.
The reminder is off until you turn it on, and until you do, Tailbook schedules nothing and never asks to send notifications — not at first launch, not ever.
When you turn on Remind me each day in Settings, and only then, Android asks whether Tailbook may send notifications (on Android 13 and later; older versions do not ask). If you allow it, Tailbook posts one notification a day at the hour you chose, listing what is overdue, what is due today and what is due within the days you chose; on a day nothing is due it posts nothing. If you refuse, the reminder stays off and every other part of the app works exactly as before.
The notification is made on your phone by Android and is not sent anywhere. On an unlocked screen it names your pets and their care items; on a locked screen it says only Pet care is due. The reminder itself is one scheduled job, kept in the app’s private storage and with Android’s job scheduler: its time, and nothing from your record.
So that a reminder survives a restart, Tailbook declares Android’s run-at-startup
permission (RECEIVE_BOOT_COMPLETED): with it, Android keeps the reminder’s job when the
phone restarts, and a reminder that fell due while the phone was off comes once, after it
starts. Without it, every restart would silently cancel the reminder. Android grants it
when the app is installed and never asks you about it, and Tailbook uses it for nothing
else.
Turning the reminder off cancels it, and turning off Tailbook’s notifications in Android’s settings also stops it.
The app contains the Google Mobile Ads SDK. It shows an occasional full-screen interstitial ad — only as you leave a pet after recording its care, never while you type and never from a reminder — plus an optional rewarded ad you can choose to watch to remove ads for 24 hours. There are no banner ads. Google may collect and process:
AdMob receives nothing from your record: no pet, no photo, no care item, no date, no cost, no note and no keywords. Like any ad in any app, an ad request does name the app it comes from. Google’s handling of the data above is governed by Google’s own policies:
Consent (EEA, UK and Switzerland): on first launch the app shows Google’s certified consent form, and you choose whether personalised ads are allowed. You can change your answer at any time from Settings → Advert privacy options inside the app. You can also opt out of personalised advertising via your device’s system settings (Android: Settings → Privacy → Ads).
None. We don’t run any backend. We have no analytics SDK, no crash reporter that phones home, no Firebase, and no custom telemetry. There is no HTTP client anywhere in the app’s own code, and the build fails if one is ever added.

Asked for only when you turn the reminder on, never at first launch; without it the
reminder stays off and everything else works.RECEIVE_BOOT_COMPLETED) — only so the daily reminder survives a
restart of your phone. Android grants it at install and never asks you about it.That is all of them. The notification permission is the only one Android ever stops to ask you about, and only when you turn the reminder on. Tailbook asks for no storage, photo or media permission: a pet’s photo comes through Android’s photo picker, care records go through Android’s share menu, and backups and CSV files through Android’s own file picker, and none of them needs one. Tailbook has no access to your location, contacts, messages, calendar, camera or microphone, it cannot browse your photos or files, and it asks for none of them. It asks for no exact-alarm permission either: the reminder is a daily list, not an alarm.
A few more permissions are merged into the final app package by the libraries the app is built on, so the list Google Play shows you is slightly longer than the one above. They are the Android Ad Services permissions, from the Google Mobile Ads SDK; wake-lock and foreground-service, from the Android scheduling library the reminder runs on, which the ads SDK brings in as well; and one permission that only lets the app’s own parts talk to each other. None is a permission Android stops to ask you about, and none is used by any code we wrote: Tailbook holds no wake lock and runs no foreground service of its own. A test reads the built app’s own merged manifest on every run and fails the build if that list ever changes.
Tailbook is for pet owners keeping their own record of their pets’ care, and is intended for adults. It is not directed to children under 13, and we do not knowingly collect data from children — and, as above, we collect no personal data from anyone.
Tailbook writes down what you say was done and works out each next due date from the dates and intervals you, or your vet, gave it. It gives no veterinary advice: it makes no diagnosis and suggests no vaccine, treatment, dose or schedule. A vet visit’s cost is your own note of what you paid; Tailbook never charges anyone and moves no money. Every page of a care record ends with the same line: The owner’s own record, kept in Tailbook. It is not a veterinary certificate and has no official standing.
If we change the data we collect or the third-party services we integrate, we will update this page and bump the “Last updated” date above. Material changes will be flagged in the app’s release notes as well.
