HTC has announced that it will delete its customers' backed-up data on its Sense cloud service.

As of 30 April HTC will shut down its HTCSense.com, after which no stored data will be accessible. The firm said that it is scrapping files including contacts, messages and call history to renovate and improve the service.

HTC said: "HTCSense.com is undergoing a renovation to improve the services and value we deliver to customers like you. Until the new services are ready, features previously available on HTCSense.com will be shutting down."

"After April 30, your data will no longer be accessible and will be deleted."

Rather than HTC backing up all the data and making it available once the service is back up and running, users are being urged to download a .zip file of all their data. This can be done on the website until 30 April.

Until Sense is re-launched HTC is recommending that users find an alternative service via the Google Play Shop. However, HTC doesn’t endorse any specific apps.

HTC apologies for any inconvenience and said to its users: "You'll be among the first to know when the new and improved services are ready."
