Have you lied about your age on Facebook? If your Facebook age is incorrect or your friends don't see it, then your age will be incorrect in the Tinder app too. If you're 21, but your Tinder profile says you're 27, you're going to get the wrong results. This can be fixed by changing your age on Facebook.
Steps

Step 1. Log in to your Facebook profile on your computer or mobile device
Tinder copies information from your Facebook profile, so in order to change your age on Tinder, you need to change it on your Facebook profile.
On Facebook, you can't change your date of birth often, so you won't be able to make changes if you've done it recently

Step 2. Click on the link "Edit profile" or the button "Update data"

Step 3. Find the "Basic Information" section and change your date of birth
Make sure the changes took effect. If you are unable to update your date of birth, most likely you have done so recently and Facebook is preventing you from changing it again.
- Some users claim that by using this help page, they were able to change their date of birth.
- Make sure your age is visible to your Facebook friends by clicking on the privacy settings drop-down.

Step 4. Launch the Tinder app on your phone

Step 5. Click on the gear-shaped button
This will open the settings menu.

Step 6. Scroll down and click on "Delete account"
You need to delete your Tinder account, after which you will lose all your matched pairs and conversations.
You can try to re-enter your account so that the information can be updated. However, users have reported that this method does not work, so deleting your account is most likely indispensable

Step 7. Uninstall the Tinder app
This is a must as it deletes the saved data on your phone.
- Removal process on iPhone - Press and hold the Tinder icon on the home screen. When the icon starts to wiggle, click on the "X" in the corner of the icon. Confirm the removal of the application.
- Uninstallation process on Android - Open the settings app and select "Apps". Scroll down the slider until you find Tinder. Click on it and then click Remove. Confirm the removal of the application.

Step 8. Re-download and install Tinder
Go to the store's app to download and install the Tinder app.

Step 9. Log in to your account using your Facebook account
A new account will be created for you, and Tinder will copy the age information from your Facebook profile.
