The product privacy notice says the desktop app sends samples of suspicious files and detection metadata to Avast's servers through CommunityIQ, and that it may 'directly analyze and maintain these artifacts in our safe environment'. It also lists the URLs of websites visited, 'malicious and non-malicious', and referrers, kept for 36 months for service provision. The support article says file-sample sharing (CommunityIQ) can be unticked in Settings ▸ General ▸ Personal Privacy. On phones, SMS Guard keeps texts that contain links or come from senders not in your contacts, with personal identifiers removed, for up to five years.

The Products Privacy Notice (last updated 25 Sep 2026) lists, for the desktop security products, 'Files identified as potential or known malware (36 months)', file metadata including file paths, application names, and 'URLs/Websites visited and associated metadata (36 months)', used among other things for 'file sample analysis'. Norton's settings article says Norton Community Watch sends information about potential security risks to Norton and, when a possible risk is detected, information on running processes, visited URLs and general system information; it can be switched off, but 'critical data will still be sent even if this option is turned off.' On phones, Safe SMS collects text messages that contain links or come from senders not in your contacts and keeps them, with personal identifiers removed, for up to five years.

The Gen Digital privacy notice says 'We do not sell your personal data to third parties', but also that 'Where permitted by applicable law, we may share personal data with third parties for advertising purposes' and that data is used 'to serve you with relevant advertising and content, both on our properties and on third-party properties'. The consent policy says free mobile apps show third-party ads from partners such as AdMob, Amazon, Facebook Audience Network and InMobi, with consent asked at installation and a paid ad-free version. The desktop app uses Google Analytics; the phone apps use Google Firebase, AppsFlyer and Singular. In the free desktop version, sharing app-usage data for Avast's own offers is on by default and cannot be switched off.

Gen Digital's General Privacy Notice, which Norton's Privacy Center says applies to Norton, says 'We do not sell your personal data to third parties', but also that the group uses data 'to serve you with relevant advertising and content, both on our properties and on third-party properties' and that 'Where permitted by applicable law, we may share personal data with third parties for advertising purposes.' Norton's cookies and analytics notice lists Google Analytics, Adobe Analytics, Quantum Metric, AppsFlyer, Singular and Firebase as analytics tools in its products. The App Store listing of the iPhone app says identifiers and usage data 'may be used to track you across apps and websites owned by other companies'. The desktop app shows promotional notifications by default; they can be switched off in Settings.
