Account & Data Deletion

Who handles your request

Requests are handled by Liangjiang New Area Weimang Topology Software Development Studio (Individually Owned Business) (Chinese legal name: 两江新区微茫拓扑软件开发工作室（个体工商户）), the developer of Topo Notes, Meridian Field and Atlas Local. You can verify our legal details on the About page.

This process applies to app accounts that may be created for optional sync features. The core features of our apps are designed to work without an account. It also applies to personal data you send us through the website contact form.

How to request deletion

Choose the method that fits your situation. We do not require you to reinstall an app or create an account to make a request.

1. If the app is installed and an account is available

   Open the app, go to Settings → Account → Delete account and follow the confirmation steps. The app will explain what will be deleted. If you cannot find the option, use the email method below.

2. Email us from the account address

   Send a message from the email address associated with the account to monyoung@microtopology.com with the subject “Account Deletion Request — [App Name]”. Include the app name, the account email and whether you want the whole account deleted or only specific data.

   Subject: Account Deletion Request — Topo Notes

   App: Topo Notes

   Account email: [the email you use to sign in]

   Request: Please delete my account and all associated personal data.

   Email for Topo Notes Email for Meridian Field Email for Atlas Local

3. Delete contact-form data

   To delete a message you sent through this website, email monyoung@microtopology.com with the subject “Data Deletion Request” and the email address you used in the form.

Do not send your password, payment card details or identity documents. We may ask you to confirm control of the account email address, but we will never ask for your password.

What happens next

If we need more time, we will explain why and give you a new date. There is no fee for a deletion request.

What we delete

• your account profile, email address, display name and account identifier;
• synced notes, survey entries, attachments and other content stored with the account;
• account preferences and identifiers associated with the account;
• website contact-form messages associated with your request, when you ask us to delete them.

Data that exists only on your device is not held in your account. You can delete it by removing the item in the app, clearing the app's storage in Android settings, or uninstalling the app. Uninstalling an app normally removes its local app data from the device, but a device backup may retain a copy according to your device or Google account settings.

What we may retain

We may retain limited records where required by law or necessary for a legitimate purpose, including:

• tax, accounting and transaction records required by applicable law;
• security and fraud-prevention logs needed to investigate abuse;
• records needed to establish, exercise or defend a legal claim;
• aggregated or de-identified data that cannot reasonably be linked back to you.

Retained data is limited to what is necessary, is protected by appropriate safeguards, and is not used for marketing. We delete it when the legal or security purpose ends.

On-device data

Topo Notes, Meridian Field and Atlas Local are designed to keep core content on your device unless you choose to export or sync it. To remove local data:

• delete the specific note, survey or entry inside the app;
• clear the app's storage in Android settings (this removes local app data);
• uninstall the app, which normally removes its local app data;
• check your device or Google backup settings if you also want to remove backup copies.

Deleting local data does not automatically delete a synced account. Use the request process above for synced data.
