Someone sends a calendar invite, and a few weeks later a strange event shows up that nobody meant to add. That moment often makes people wonder which apps can actually see or edit their calendar in the first place.
The short answer is that both iPhone and Android let you review every app with calendar access and turn that access off app by app, right from your phone’s privacy settings. This does not delete events that are already on your calendar — it only stops future access.
This article walks through how to find the calendar permissions menu on both platforms, what to do once you are there, and what to check if you still see unwanted events after revoking access.

🔍 What to Check First
Before changing any settings, it helps to know what calendar permission actually controls. When an app has calendar access, it can usually read your existing events, add new ones, and sometimes edit or delete entries depending on how the app was built.
This is different from an app simply sending you a calendar invite through email or a messaging app. A one-time invite you choose to add is not the same as an app having ongoing access to your entire calendar.
Start by thinking about which apps on your phone genuinely need to see your schedule. A video calling app that creates meeting links, a travel app that adds flight times, or a work app that syncs meetings are reasonable candidates. A game or a flashlight app asking for calendar access is not.
It is also worth remembering that an app only shows up in the calendar permissions list after it has asked for access at least once. If an app never asked for permission, it will not appear there at all, which is a quick way to confirm you never approved it.
💡 Key point: Calendar access lets an app read or add events going forward — it does not automatically remove anything already on your calendar.
⚙️ Step-by-Step: iPhone Calendar Permissions
On an iPhone, calendar permissions live inside the main privacy menu, separate from individual app settings. This makes it easy to see every app with access in one place instead of checking apps one at a time.
Here is the general flow to follow:
- Open Settings on your iPhone.
- Tap Privacy & Security, then select Calendars.
- Review the list of apps shown. Each app shows its access level, such as Full Access, Add Events Only or None.
- Turn off access for any app you do not want using your calendars.
Every app that appears in this list has asked for calendar access at some point, whether you approved it right away or were prompted later while using a feature inside the app. Turning a toggle off does not uninstall the app or affect its other permissions, like contacts or photos — it only changes calendar access.
If you turn access back on later, the app usually regains the same level of access it had before, though some apps may ask you to confirm again the next time you open a calendar-related feature inside them.
Apple’s naming for this menu has stayed fairly consistent, but if a future update moves things around, searching Calendars in the Settings search bar will take you to the right screen.
📱 Step-by-Step: Android Calendar Permissions
Android organizes permissions a bit differently than iPhone, and the exact wording can vary depending on your phone’s manufacturer and Android version. The general path, though, stays similar across most devices.
- Open Settings on your Android phone.
- Go to Security & privacy (sometimes labeled simply Privacy).
- Look for Privacy controls, if your phone shows that option, then tap Permission manager.
- Select Calendar to see every app with calendar access.
- Choose an app, then set its permission to Don’t allow.
If you would rather check one specific app instead of browsing the full permission list, there is a second path that works just as well:
- Open Settings, then tap Apps (or See all apps if apps are not shown directly).
- Select the app you want to review.
- Tap Permissions.
- Find and select Calendar, then adjust the setting.
Because Android phone makers customize their settings menus, the exact labels for Security & privacy and Permission manager can differ by brand and software version. If you cannot find either menu by browsing, searching Permission manager or Calendar directly in the Settings search bar is usually the fastest way to reach the right screen.
📱 iPhone vs. Android Differences
Both platforms let you see and revoke calendar access, but they organize the information differently, which can be confusing if you switch between an iPhone and an Android phone or help family members with both.
| Platform | Menu Path | Notes |
|---|---|---|
| iPhone | Settings > Privacy & Security > Calendars | Single consistent list across all iPhones |
| Android | Settings > Security & privacy > Permission manager > Calendar | Menu names and location can vary by phone maker |
| Android (per app) | Settings > Apps > select app > Permissions > Calendar | Useful when checking a single app rather than browsing all |
On iPhone, Apple controls the operating system and the Settings app design, so the path stays the same regardless of which iPhone model you own, as long as it runs a reasonably current version of iOS.
Android is different because manufacturers like Samsung, Google, and others customize the settings interface on top of the core Android system. This is why the Security & privacy or Privacy label, and the presence of a Privacy controls step, can vary from phone to phone.
Despite the differences in wording, the underlying concept is the same on both platforms: a central permission list where you can see every app that asked for calendar access and switch it off individually. Neither platform requires you to uninstall an app just to remove its calendar permission.
✅ Useful Ways to Use Permission Reviews
Reviewing calendar permissions is not just a one-time cleanup task. It can be a useful habit, especially after installing new apps or noticing unfamiliar events appear.
A few situations where checking this list is particularly helpful:
- ✅ After installing a new app that asked for calendar access during setup
- ✅ When you notice unexpected events, reminders, or invites appearing on your calendar
- ✅ Before lending your phone to someone else temporarily, if you want to limit what apps can modify your schedule
- ✅ After a major phone or app update, since permission prompts sometimes reappear
Some people prefer to only grant calendar access the moment an app needs it, then revisit permissions every few months to remove anything no longer necessary. Others simply grant access once during setup and rarely revisit it. Either approach is reasonable, as long as you check in occasionally.
It is a good idea to think of this the same way you think about reviewing subscriptions or app notifications: not something you need to do constantly, but worth a quick look periodically so permissions stay aligned with how you actually use your apps.
⚠️ If It Does Not Work
Occasionally, turning off calendar access does not seem to solve the original problem, usually because the issue is not about permission at all.
If you revoked access for an app but still see events you do not recognize, the events were likely already added to your calendar before you changed the permission. Removing access prevents future changes, but it does not clean up past ones.
In that case, check which specific calendar the event belongs to. Many calendar apps let you view multiple calendars at once — a personal one, a work one, and sometimes calendars automatically created by other services. Removing the individual event, or removing the entire calendar it belongs to, usually clears it out.
If an app does not appear in the permission list at all, even though you remember granting it access at some point, it is possible the app was deleted and reinstalled, which can reset its permission history. Reinstalling the app and going through its calendar permission prompt again should let you confirm or deny access properly.
⚠️ Watch out: Turning off calendar access will not delete events the app already added — you need to remove those events or their calendar separately.
🛡️ Things to Watch Out For
Calendar permissions are generally straightforward, but a few details are easy to overlook.
First, remember that calendar spam — unwanted event invites that appear without you adding them — is a separate issue from app permissions. According to Google Calendar Help, there are dedicated steps for blocking calendar spam on Android, which is different from managing which installed apps can access your calendar.
Second, revoking access from an app you actually use for scheduling, like a work calendar tool or meeting app, may cause that app’s calendar features to stop working properly. If an app suddenly cannot create or sync events after an update, double-check that its calendar permission was not accidentally turned off.
Third, because this topic involves personal data and scheduling information tied to your accounts, it is a good idea to check your phone’s official help page or contact Apple Support or Google’s Android Help directly if you run into a setting that does not match what is described here, since exact wording can shift after software updates.
Finally, keep in mind that granting calendar access again later generally restores an app’s previous level of access, so there is no risk of losing functionality permanently just by testing whether turning permission off causes problems.
🙋 Frequently Asked Questions
Q. Will turning off calendar access delete events the app already created?
No. Revoking permission only stops future access. Any events already added will remain until you delete them manually or remove the calendar they belong to.
Q. Can an app see my calendar without ever asking for permission?
On both iPhone and Android, an app generally must request calendar access before it can read or add events, and it only appears in the permission list after making that request.
Q. Why does an app I never approved still show up in the list?
It likely requested access at some point, even if you do not remember approving it, possibly during setup or while using a specific feature inside the app.
Q. Does revoking access affect calendar invites sent through email or messages?
No. A calendar invite you manually accept through email or a messaging app is separate from an app having ongoing permission to access your calendar directly.
Q. Why do Android menu names look different on my phone compared to someone else’s?
Android phone makers customize the settings interface, so labels like Security & privacy or Privacy controls can vary. Searching Permission manager in Settings usually works regardless of the exact wording.
Q. If I reinstall an app, do I need to set its calendar permission again?
Yes. Reinstalling an app can reset its permission history, so you will likely see the access prompt again and need to approve or deny it.
Q. Is there a way to check just one app instead of the full list?
On Android, yes — go to Settings, then Apps, select the app, tap Permissions, then Calendar. On iPhone, the full Calendars list under Privacy & Security is the main way to review access.
