In general, no, someone cannot track your location through your WhatsApp posts unless you have explicitly shared your location or enabled location sharing with that person.

WhatsApp allows you to share your live location with individual contacts or groups, but you have to explicitly turn on this feature and select the duration of time for which you want to share your location. Once the time limit is up, your location sharing will automatically stop, and the other person will no longer be able to see your location.

Similarly, WhatsApp also has a feature called “location sharing” that allows you to share your current location with a contact or group for a one-time period. This feature can be accessed by tapping the “+” button in the chat and selecting “Location” > “Share live location” or “Send your current location”.

However, if you have not shared your location with someone or enabled location sharing, it is not possible for them to track your location through your WhatsApp posts.

It is worth noting, though, that if you are sharing your location with someone, they will be able to see your location information for the duration of time that you have specified, so be sure to use location sharing with caution and only with people you trust.
