Vivichi (“the app”) is developed by Syphen. This privacy policy explains what information the app handles, what is shared with third parties, and the choices you have.
Everything you enter in Vivichi (your pet’s name and species, habit names and schedules, streaks, XP, coins, unlocked items, achievement progress and settings) is stored locally on your device only, in Android’s private app storage. The developer has no server, you don’t need an account, and this data is never uploaded or shared by Vivichi.
If you uninstall the app, this data is permanently deleted from your device.
Vivichi shows two kinds of ads, and no ads at all to Premium users:
Ads are provided by Google AdMob. To serve and measure ads and to prevent fraud, Google may collect and process information from your device, including:
This information is collected by Google, not by the developer, and is handled under Google’s Privacy Policy. You can learn how Google uses information from apps that use its services at policies.google.com/technologies/partner-sites.
Google may also share this information with its ad technology partners, which help select, deliver and measure the ads you see. The consent form shown in the app lists these partners in full — open List of partners inside it to see the current list — and Google describes how it manages them at support.google.com/admob/answer/9012903. If you are in the European Economic Area, the UK or Switzerland, no partner may use your data for personalised advertising unless you consent, and you can withdraw or change that consent at any time under More → Ad privacy choices.
Your choices:
Vivichi Premium is a one-time purchase made through Google Play Billing. Payment is handled entirely by Google Play. The developer never sees or receives your card or payment details. Vivichi only receives confirmation from Google Play of whether your Google account owns Premium, so it can unlock Premium features and restore them on a new device. Purchases are governed by Google Play’s Terms of Service and Google’s Privacy Policy.
Vivichi uses Android’s local notification and alarm system to remind you about your habits. These reminders are scheduled and triggered entirely on your device, and no data about your habits is sent anywhere to make this work.
If you turn on the optional pet status panel, Vivichi shows an ongoing notification with your pet’s name, its health, and your next habit with a countdown. This is generated on your device and is not sent anywhere. You can turn it off at any time under More.
The app requests the following permissions, used only for their stated purpose:
If you use the in-app “Share Streak” feature, an image is generated on your device and passed to your phone’s share sheet. It is only sent to the app or contact you personally choose.
Vivichi is not directed at children under 13, and the developer does not knowingly collect personal information from children. The advertising services described above are provided by Google. If you believe a child has provided information through the app, contact the email below.
The developer does not hold any of your data, so there is nothing for the developer to delete. Your in-app data is erased when you use More → Reset all data or uninstall the app. For data collected by Google for advertising, you can manage or delete it through your Google account and device ad settings described above.
If this policy changes, this page will be updated and the “Last updated” date above will change.
