The social media platform has responded following a devleoper trial of the device's latest iOS 14 update, which sees users notified whenever an app accesses the handset's clipboard.
Security researchers previously flagged TikTok - as well as 52 other apps - as regularly seeking clipboard access.
In a statement to BBC, the company clarified: "Following the beta release of iOS14 on June 22, users saw notifications while using a number of popular apps.
"For TikTok, this was triggered by a feature designed to identify repetitive, spammy behaviour.
"We submitted an updated version of the app to the App Store removing the anti-spam feature to eliminate any potential confusion."
The platform - which is owned by Chinese firm Bytedance - added that the feature was never enabled on Android devices.
Professor Alan Woodward - a cyber security expert at Surrey University - said: "People ought to be aware that on mobile devices, in order to try and be helpful they can be doing things that are slightly unexpected.
"It's not ideal but in this case there is no evidence that it was sending the data anywhere other than the phone. There's no cause for alarm."
