HydroFast data deletion

HydroFast Data Deletion Request

This page explains how to delete data for HydroFast, the Android water and fasting tracker developed by Syed Shahbaz Hussain. HydroFast does not create or require user accounts, so HydroFast tracking data stays on your own device and is deleted from the device. If you previously sent a Help and Support request, you can ask for that information to be deleted by email.

HydroFast does not use accounts

HydroFast does not create or require a user account, username, or password for normal app use. There is no profile held on a HydroFast server to sign in to. Deleting HydroFast data means removing the data stored on your device and, separately, asking for deletion of any Help and Support request you chose to send.

Data stored on your device

HydroFast keeps its normal tracking and profile information on your Android device so the app works offline. Depending on what you use, this can include:

  • Hydration logs and water intake history
  • Fasting plans, fasting sessions, and fasting history
  • Daily hydration goal
  • Profile information used by the app, such as name, optional gender, weight, wake and sleep times, and fasting experience or preference
  • Streaks and achievements
  • Reminder settings and reminder state
  • Theme preference, ml/oz unit preference, and other app settings
  • PDF reports generated on the device, saved to the file location you choose

This information stays on your device. It is not automatically uploaded to a HydroFast server, so there is no HydroFast cloud copy to delete on your behalf.

Delete data stored on your device

You can remove locally stored HydroFast data in any of these ways:

  1. Inside the app. Open HydroFast, go to Settings, choose Reset All Data, then confirm.
  2. From Android settings. Clear HydroFast app storage in your device settings.
  3. Uninstall. Removing HydroFast from your device removes the app data stored with it.

Deleting locally stored app data is permanent and cannot be undone after you confirm it. A PDF report you already saved or shared is an ordinary file, so it is not removed by Reset All Data. Delete those the same way you delete any other file on your device or in the app you shared them with.

What local deletion does not cover

Using Help and Support is voluntary. If you chose to send a support request, that request was transmitted to the HydroFast support service so it could be read and answered.

Reset All Data, clearing app storage, and uninstalling HydroFast affect your device only. They do not automatically delete a support request that was already submitted. To have that information removed, send a deletion request by email.

Request deletion of support information

Email your request to the HydroFast support address:

Send your request to

support@syedshahbazhussain.com

Subject
HydroFast Data Deletion Request
Include
The email address you used for the support request
Include if possible
The approximate date you submitted the request

These details are needed to locate the matching records. Without them, a request cannot reliably be matched to the right support submission.

Request Data Deletion

Support information that may be deleted

A deletion request can cover the information sent with your Help and Support submission:

  • Name, if you provided it
  • Email address used to submit the request
  • Support category, subject, and message
  • Optional screenshot you attached
  • App version
  • Android version
  • Device model
  • Locale or language-region setting
  • Randomly generated installation identifier associated with the support request

The installation identifier is generated randomly and stored on your device for support submissions. It is not an advertising identifier, IMEI, or device serial number.

Data we may retain

Support information is deleted on request except where keeping a limited record is genuinely necessary. Where that applies, only what is needed for the specific purpose is kept, and it is not used for advertising or profiling. This can include:

  • Legal obligations. Records that must be kept to comply with applicable law, or to establish, exercise, or defend legal claims.
  • Security and abuse prevention. Limited records, such as an installation identifier associated with spam or abusive submissions, kept so support-request limits and abuse protections continue to work.
  • Fraud prevention. Information needed to investigate or prevent fraudulent or malicious use of the support channel.
  • Ordinary email records. The email conversation you started with us, where it is needed to show that the request was handled.

Anything retained on these grounds is removed once the purpose no longer applies. To ask whether any of your information was retained after a deletion request, reply on the same email thread.

Data deletion FAQ

Do I need a HydroFast account to delete my data?

No. HydroFast does not create or require user accounts, so there is no account to sign in to. Tracking data is stored on your Android device and is removed from the device itself.

How do I delete HydroFast data stored on my device?

Open HydroFast, go to Settings, choose Reset All Data, then confirm. Clearing HydroFast app storage from Android settings or uninstalling the app also removes locally stored app data.

Does resetting or uninstalling HydroFast delete my support request?

No. Resetting app data, clearing app storage, and uninstalling HydroFast affect your device only. A Help and Support request you already submitted was sent to the support service and is not deleted automatically.

How do I request deletion of a support request I already sent?

Email support@syedshahbazhussain.com with the subject HydroFast Data Deletion Request. Include the email address you used for the support request and, where possible, the approximate date you submitted it, so the matching records can be located.

What support information can be deleted?

The name, email address, category, subject, message, optional screenshot, app version, Android version, device model, locale, and the installation identifier associated with your support request.

Are my PDF reports deleted too?

HydroFast reports are generated on your device from locally stored activity. A PDF you saved is an ordinary file in the location you chose, so it is removed the same way you delete any other file on your device or in the app you shared it with.
