Margin
A short summary
Margin is a home screen. Notes and to-dos are stored privately on your phone. They stay on the device unless you turn on a sync service, or you sign in to a Google account for Android’s automatic backup. We do not run an account system, and we do not sell your data.
Some features talk to other companies only if you turn them on or use them: optional to-do and note sync (Google Tasks, Todoist, Notion, Tasks.org, OpenTasks, or a Markdown folder), Open-Meteo for weather, Google AdMob for the Settings ad and the optional Premium video, and Google Play for a Premium subscription. Android may also include some of Margin’s on-device data in your device backups, as described below.
Who we are
We are Margin. For questions or requests about this policy, write to support@marginlauncher.top.
Information that stays on your phone
Notes and to-dos are stored privately on this device only. Nothing from them leaves the phone unless you turn on a sync service in Settings › Sync, or you sign in to a Google account for Android’s automatic backup. Margin keeps the following in its private app storage, in a local database and preferences file:
- Notes you write, including titles, body text, categories, and links you make between a note and a to-do.
- Note attachments — photos, video, and voice memos — as files only this app can read. Voice notes are recorded on the device with the microphone; Margin does not send them to a transcription or cloud-audio service.
- To-dos, including local lists. A link from a to-do to a note is stored only in Margin and is not sent to Google Tasks or to other sync services.
- Settings, such as theme, clock style, accent, the name used on the Morning Edition masthead, pinned edge apps, the assistant bar, and whether Premium is active on this phone.
- A short launch log Margin keeps itself, so it can rank apps you open from the launcher. This log stays on the device.
- Cached weather, if you use weather, and a cached copy of the last forecast.
We do not receive this information. Margin has no analytics or crash-reporting service of its own, and this website does not set analytics cookies.
Information you can choose to share
Optional sync services
Margin works fully offline. Sync is off until you turn on a service in Settings › Sync. When you do, Margin connects directly from your device to that service. We run no sync server, and we never receive your notes, to-dos, or tokens. Transfers happen only at your direction. Connections use HTTPS. For steps to connect a service, see Sync & services.
| Service | What is sent | Where | Direction |
|---|---|---|---|
| Google Tasks | To-do title, done state, list name | Google Tasks API (tasks.googleapis.com), after you sign in with Google | Two-way |
| Todoist | To-do text, done state, completion date; a “Margin” project | api.todoist.com, using the API token you paste | Two-way |
| Notion (to-dos) | To-do title and done state | api.notion.com, only for the database you shared with your integration | Two-way |
| Notion (notes) | Note title, category, and text (as paragraphs, headings, and checklists) | api.notion.com, only for the database you chose | One-way, device to Notion |
| Tasks.org / OpenTasks | To-do title and done state | Stays on your device. It goes to those apps through Android’s content providers, and they may sync it onward (for example with DAVx5) under their own policies | Two-way |
| Markdown / Obsidian folder | Note text and to-do checklist as .md files | A folder you pick with Android’s file picker. Margin can access only that folder | Export; import only if you turn it on |
- Tokens: Todoist and Notion tokens are encrypted with an Android Keystore key that never leaves your device. They aren’t included in backups and are deleted when you tap Disconnect.
- Media: Photos, videos, and voice notes are never uploaded to any sync service.
- Network: Margin uses the network for the services you turn on (sync and weather), for ads and Play Billing when those features are used, and for Google sign-in if you use Google Tasks.
- Permissions: The optional Tasks.org / OpenTasks task permissions are requested only when you connect those apps.
- Third parties: Data sent to a service is governed by that service’s privacy policy: Google, Todoist (Doist), Notion Labs, or the task app you chose.
- Removing data: Disconnect a service at any time in Settings › Sync. Disconnecting stops sync and deletes the stored token. It doesn’t delete copies already in the service. Remove those in the service itself.
Google Tasks (optional)
If you turn on Google Tasks in Settings › Sync, Margin asks Google, through Google Play services, for permission to use only the Google Tasks scope (https://www.googleapis.com/auth/tasks). It does not request Gmail, Drive, Calendar, or other Google scopes.
When sync is on, Margin exchanges the title and completed status of to-dos in your Pocket notebook with a list named “Margin” in your Google Tasks account (it will create that list if needed). You can also link other Google Tasks lists you already have. Sync is two-way; the newest edit wins. The access token is held in memory only, is never written into the app package, and is not logged.
Turning sync off in Settings stops future sync. It does not delete the “Margin” list, or any tasks, from your Google account. You can delete those in Google Tasks, and you can revoke Margin’s access in your Google Account’s third-party app settings.
Weather (optional)
The weather widget and the optional weather line under the clock use Open-Meteo, which does not require an account. If you type a city in Settings, Margin sends that name to Open-Meteo’s geocoding service, then requests a forecast for the resulting coordinates. If you haven’t typed a city and you have allowed coarse location, Margin uses the last known coarse location from Android (coordinates are sent rounded to three decimal places) and labels the place “Your area.” The forecast is cached on the phone. Location is used only to fetch weather, not to track you.
Ads and the advertising ID
If you are not on Premium, Margin may show one native ad on the Settings page, served by Google AdMob. You can also watch a rewarded video ad to unlock Premium for 24 hours. Premium users are not shown either ad, and Margin does not load ads for them.
Before ads are requested, Margin uses Google’s User Messaging Platform (UMP) to ask for a privacy choice where a published message applies (for example in the EEA, UK, and some US states). You can review or change that choice later in Settings › Privacy & ads, in regions that require it. Ads are not loaded until that choice allows it, or where a form isn’t required.
To serve and measure these ads, the AdMob SDK may use the Android advertising ID and related Google advertising services, including Privacy Sandbox signals such as Topics and Attribution on versions of Android that support them. Google’s use of that information is described in Google’s Privacy Policy and AdMob documentation. We do not sell the advertising ID or use it for our own marketing lists.
Google Play Billing (optional)
If you subscribe to Margin Premium for $1.99 a month, payment is handled by Google Play. Margin reads from Play whether the subscription margin_premium_monthly is active, and stores that status on the phone. Play is the source of truth when it answers. We do not receive your full payment card details. Manage or cancel the subscription in the Play Store. Google’s handling of purchase data is described in Google’s Privacy Policy.
Android backup and device transfer
Margin allows Android Auto Backup. If backups are enabled on your phone and you are signed in to a Google account, Google may store a copy of Margin’s database and settings (notes, to-dos, and preferences) in your Google account’s device backups. Note attachments are left out of cloud backup so a large photo or video cannot cause the whole backup to fail. A phone-to-phone device transfer can include those attachments. You can turn off app backups in Android settings, and you can delete device backups from your Google account.
If you do not sign in to a Google account and you do not turn on a sync service, notes and to-dos remain private and local. Android’s automatic backup does not run without a Google sign-in. Sync only starts after you turn on a service in Settings › Sync. Tokens you paste for Todoist or Notion are encrypted with a key that stays on the phone, and they are not included in Android backups.
Assistant handoff and third-party widgets
If you point the bottom bar at an assistant, text you send is handed to that app through a standard Android intent. We do not receive that text. Widgets you add from other apps are shown by those apps and follow their own policies.
Permissions, and why they’re there
Margin asks for a permission when the feature that needs it is used, except for a few that a home screen has to declare up front. Denying a permission turns that feature off; the rest of the app still works.
| Permission | What Margin uses it for |
|---|---|
| Internet and network state | The sync services you turn on, weather, ads, Play Billing, and Google sign-in if you use Google Tasks. |
| Calendar (read) | Upcoming events on the Calendar widget, the optional “next event” line under the clock, and Day Timeline — only after you allow it. Events stay on the device. |
| Contacts (read) | Starred contacts on the Contacts widget, only after you allow it. Names and numbers stay on the device. |
| Coarse location | Weather, only if you haven’t typed a city and you allow it. Margin does not request fine location or background location. |
| Usage access | Today’s screen time on the Screen time widget, Recents, and optional ranking of apps opened outside Margin. This data stays on the device. You grant it in system settings. |
| Microphone | Voice memos in the note editor, only after you allow it. Audio is saved on the phone and is not uploaded by Margin. |
| Health Connect — read steps | Today’s step count on the Steps widget. Margin never writes health data, never sends it anywhere, and keeps nothing beyond the number on screen. You can remove the permission in Health Connect. |
| Notification policy (Do Not Disturb) | The Quiet toggle on the built-in toggles widget, only after you allow access. Margin does not read the contents of your notifications. |
| Notifications | Declared so Margin can show system notifications if a feature needs them. Updates for the edition on Google Play come from Google Play. Margin does not use this permission to send marketing messages. |
| Install and delete packages | The Play edition does not install its own updates. “Uninstall” on an app in Margin opens the system uninstall dialog. Margin can ask Android to delete a package only in that user-started flow. |
| Expand status bar, bind widgets | Ordinary home-screen behavior: opening the notification shade from a gesture, and hosting widgets you add. |
| Tasks.org / OpenTasks | Requested only when you connect those apps, so Margin can read and write to-dos through them. |
| Advertising ID and ad services | Included with Google’s ads SDK, for the Settings ad and the rewarded Premium video, as described above. |
| Billing | Google Play purchases for the optional monthly Premium plan. |
Margin also looks up which apps on the phone can be launched, and which can provide a widget, so it can list them. It does not request the “query all packages” permission. The flashlight tile on the toggles widget uses the camera flash only; Margin does not take photos for that tile.
Google’s ads and billing libraries may also declare technical permissions such as a wake lock or a foreground service. Margin does not use those to run a persistent background service of its own.
We don’t sell your data
We do not sell your personal information, and we do not share notes, to-dos, attachments, contacts, calendar events, location, usage, health, or microphone recordings with third parties for their marketing. Independent companies you choose to use (Google, Todoist, Notion, a task app such as Tasks.org or OpenTasks, Open-Meteo, an assistant app) process what you send them under their own policies, including to show ads if you watch a video or see the Settings ad.
Children
Margin is a general-audience home screen and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through Margin, contact us and we will help you delete what we can (in practice, that information lives on the device or in a service the child’s guardian controls, such as a Google account).
Your choices, and how to delete data
- Delete a note or to-do inside Margin. Deleting a note removes its attachments from the phone and unlinks it from to-dos; the to-dos themselves remain unless you delete them too.
- Uninstall Margin to remove its on-device database, settings, and attachments from that phone.
- If you use Android backup, also remove or wait out device backups in your Google account if you want those copies gone.
- Disconnect a sync service in Settings › Sync. That stops future sync and deletes the stored token. It does not delete copies already in the service; remove those in the service itself (for example the “Margin” list or project, or pages in Notion).
- If you use Google Tasks, you can also revoke Margin’s access in your Google Account’s third-party app settings.
- Reset or opt out of the advertising ID in Android settings, and use Settings › Privacy & ads in Margin where the consent form is available.
- Revoke Health Connect, calendar, contacts, location, microphone, usage access, or notification-policy access in Android or Health Connect settings.
- Cancel a Premium subscription in Google Play.
Because we do not keep a copy of your notes or to-dos on our servers, we cannot remotely erase what’s only on your phone. Write to us if you need help with a request, and we will tell you what we can and cannot do.
Changes
If we change this policy in a way that matters, we will update the effective date on this page. Continued use of Margin after an update means you accept the revised policy.
