"imo automatically collects certain information that your mobile device sends when you use our mobile application, like an advertising identifier, IP address, user settings, phone model, SIM serial, connection type (e.g., cellular or WiFi), mobile carrier, push notification token, and the operating system of your device. If our app has your permission, we collect contact information from your mobile address book to connect you to your friends on imo."

imo collects extensive device data including SIM serial number, mobile carrier, and full contact address book, much of which goes beyond what a messaging app strictly requires.

"When you use our Mobile App, we may collect and store information about your location by converting your IP address into a rough geo-location or by accessing your mobile device's GPS coordinates or coarse location if you enable location services on your device. How do we use it? To improve and personalize our Services and to target advertisements that may be more relevant to you."

imo collects both precise GPS coordinates and IP-based geolocation, and uses this location data not just for core functionality but for advertising targeting purposes.

"We may modify our Privacy Policy from time to time. When we make changes, we will notify you by making the revised version available on this webpage, and will indicate at the top the date of the latest revision. You understand and agree that your continued access to our Service after any posted modification to the Privacy Policy indicates your acceptance of those modifications."

imo can change the privacy policy unilaterally at any time, with no direct notification to users — simply posting an update on the webpage counts, and continued use equals acceptance.

"We may allow third-party advertising partners to collect the advertising identifier and IP address from your mobile device and set tracking tools on your browser (e.g., cookies) to collect information regarding your activities. When you use imo to communicate with persons who are located outside the United States, we share information necessary to enable those communications with the third party companies that operate the imo-branded services for non-U.S. users. This information includes your Account Information, Profile Information, Message Information, IP address, and phone make and model."

imo shares extensive personal information — including message content, profile data, and device identifiers — with third-party advertising partners and international imo operators.

"Please be aware that, for technical reasons, when you delete messages, your chat history, or your account, related information may persist for a limited period of time in our backup copies. Even if you delete your entire account, we may retain limited information about your mobile device for the purposes of fraud detection and enforcement of our Terms of Service."

Even after account deletion, imo retains device information indefinitely for fraud detection, and deleted data persists in backups for an unspecified period.

"Third party advertisers and advertising networks may use advertising identifiers collected from your imo app to deliver ads they believe are relevant to you in other third party apps. We may allow third-party advertising partners to collect the advertising identifier and IP address from your mobile device and set tracking tools on your browser (e.g., cookies) to collect information regarding your activities."

imo enables third-party advertisers to collect advertising identifiers and set tracking cookies to follow users across other apps and websites for targeted advertising.

"Please be aware that, for technical reasons, when you delete messages, your chat history, or your account, related information may persist for a limited period of time in our backup copies (though it will not be visible to other users). Even if you delete your entire account, we may retain limited information about your mobile device for the purposes of fraud detection and enforcement of our Terms of Service."

Deleted account data survives in backups for an unspecified duration, and device information is retained indefinitely even after full account deletion.
