DELETE YOUR
ACCOUNT

Do You Have an Account?

HowFast can be used without an account — drag-strip timing, the run logbook, vehicle profiles, and ET predictions are stored locally on your device and are not tied to any account. If you never signed in with Apple or Google, you do not have a HowFast account, and there is no server-side account to delete. To remove locally stored data in that case, simply delete the app from your device.

If you did sign in to enable DynoLog Cloud Sync (which uploads your runs so they appear automatically in the DynoLog companion app), an account exists on our servers and the steps below apply to you.

One Account Across HowFast and DynoLog

HowFast and DynoLog are both published by DtimesTwo Technologies LLC and share a single account system. If you sign in to both apps with the same Apple or Google login, you have one account used by both.

Deleting your account — whether you do it in HowFast or in DynoLog — removes that shared account and all data associated with it across both apps, including any DynoLog builds you published. If you only use HowFast, only your HowFast data exists and is removed.

How to Delete Your Account

The fastest way is in the app: open Settings → DynoLog Cloud Sync (where you signed in) and choose Delete Account. Your account and cloud data are removed immediately. To request deletion by email instead, follow these steps:

• Send an email to support@dtimestwo.com from the email address associated with your account, or include it in the message.
• Use the subject line "HowFast Account Deletion Request".
• In the message, state that you want your account deleted, and tell us whether you signed in with Apple or Google so we can locate your account.
• We may contact you to verify that the request is genuinely from the account owner before we proceed.

What Is Deleted, What Is Kept

Data that is deleted. When your account is deleted, we remove the data associated with it, including:

• Your account profile (display name and avatar, if set)
• Your synced performance runs uploaded from HowFast (DynoLog Cloud Sync)
• Any DynoLog data tied to the same account — published builds and their public pages, comments, likes, and follow relationships
• Your device identifier and push notification tokens

Data stored only on your device. Drag-strip runs, logbook entries, vehicle profiles, and prediction data that you created and kept locally are stored on your device, not on our servers (unless you synced them). This local data is removed when you delete the app from your device.

Data that may be retained. We may retain limited information after deletion where we are required or permitted to do so, including:

• Records required to comply with legal, tax, accounting, or regulatory obligations
• Moderation records relating to content or conduct that violated our Terms of Use, retained to enforce our community guidelines and prevent ban evasion
• Information already aggregated or anonymized such that it can no longer be associated with you

Retained records are kept only as long as necessary for the purposes above and are then deleted or anonymized.

Processing Time

Deleting your account in the app takes effect immediately. We aim to process verified email deletion requests within 30 days of receipt. In-app purchases are processed by Apple or Google and are governed by their respective refund and purchase policies; deleting your account does not request a refund.
