|---|---|---|

What Simplish Planner & To Do List's label means for you
Simplish Planner & To Do List's label has 1 type under “Data Used to Track You”, 1 type under “Data Linked to You”, 1 type under “Data Not Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.
Tracking is the declaration that most separates apps. It means usage data from Simplish Planner & To Do List can be combined with data from other companies to target or measure ads, or shared with data brokers. On iOS 14.5 and later, the app must ask your permission before tracking you through the advertising identifier; answering “Ask App Not to Track” blocks that identifier and tells the developer you have declined.
None of the data types fall into the categories most people consider sensitive: health, financial information, precise location, contacts, browsing history or the content you create.
Calendars reveal where you will be and who you meet. Planner apps may also read your other calendars and reminders. Check the Calendars permission level (full access or add-only) in Settings › Privacy & Security › Calendars.

Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.

What the label cannot tell you
- A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what Simplish Planner & To Do List sends.
- It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
- Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
- Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
- Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.
