Messo
Privacy Policy
Last updated: June 2025
On-device only · No account required
Overview
This Privacy Policy is provided by Stanislav Morozov (“we”, “us”, or “our”), independent developer of Messo.
Messo is a to-do list, task manager, and notes app designed with privacy as its foundation. We do not collect, store, or transmit your data on our servers. Everything you enter stays on your device.
What Data We Collect
Messo does not collect any data on our servers.
All information you enter — including to-do lists, tasks, notes, countdowns, and spaces — is stored exclusively on your device using Apple’s on-device storage. This data never leaves your device.
Messo does not access, collect, or transmit this data to the developer or third parties.
On-Device Storage Only
Messo has no servers and no cloud infrastructure for your app data. There is no account system because there is nothing to log into. Your data exists solely on the iPhone or iPad where you installed the app.
When you delete the app, all data is deleted with it. We have no copy of your information.
Third-Party Services
We do not integrate third-party analytics SDKs, advertising networks, or social media SDKs. We do not use services such as Firebase, Mixpanel, Amplitude, Facebook SDK, Sentry, or similar tools.
Apple Services
If you have enabled Share iPhone Analytics in your iOS settings, Apple may share anonymized crash reports and performance diagnostics with us. This data does not include your app content or anything that identifies you.
Apple may also provide aggregated, anonymized App Store analytics (such as downloads and page views) that cannot be used to identify individual users.
Notifications
If you enable reminders related to tasks and countdowns, these are scheduled locally on your device using iOS’s notification system. No data is sent to external servers to enable these notifications.
Children’s Privacy
Messo is not directed at children under the age of 13. We do not knowingly collect information from children. We do not collect personal data on our servers.
Changes to This Policy
If we make any changes to this Privacy Policy, we will update the date at the top of this page and post the revised policy here. Material changes will be described in the updated text.
