Contact & data deletion

murmur

This page is where you can contact us about murmur (the "App"), ask us to delete your data, and, if you represent a shop or a facility, send us a request about it. The App does not create accounts, so you never register a name or email address.

1. Delete your data in the App (the most reliable way)

In the App, Settings › Account › Delete all my data deletes everything tied to this device at once. Afterwards the App starts over from the beginning. This cannot be undone. This feature is in versions that support it (on iPhone, version 1.2.1 and later). If you do not see it in Settings, update the App to the latest version, or ask us as described in 3 below.

• Your murs (text, position, photo, translations) and the replies on them
• Your mark (name, notice, photo; if it was pinned onto a place such as a shop, it is unpinned)
• Your musts (the text and photo of notes you left on places, and the records of the places you wrote on) and your place requests
• Blocks, appeals, and records of violations
• Your push token and notification records, and photo send counts
• Subscription records
• The device's anonymous ID and session

Replies you left on other people's murs are kept with their text removed, so the threads stay readable, and are no longer tied to your device. Reports you made are kept, without the link to your device, for up to 90 days after handling, because we need them for moderation. See the Privacy Policy for details.

2. About your subscription

Deleting your data does not cancel an App Store or Google Play subscription, and you will still be charged. You can cancel only in the store:

• iPhone: Settings › your name (Apple Account) › Subscriptions
• Android: Google Play Store › Payments & subscriptions › Subscriptions

If you start the App again after deleting and tap "Restore purchases" on the premium screen, an active subscription comes back as the paid plan.

3. If you cannot delete in the App (older version, or the App already removed)

If your version of the App does not have Delete all my data in Settings, or you have already removed the App, you can ask us through the contact form below. Because the App has no accounts, we cannot identify you by name; we find and delete your posts from the details you give us. Most data also disappears on its own:

• Murs are deleted automatically after the period chosen when posting (1–48 hours, up to 7 days on the paid plan).
• Other records are deleted after the retention periods in the Privacy Policy.

When you ask us to delete your data, please include the following in the contact form. You do not need to give your name.

• That this is a data deletion request
• For each mur: the approximate date and time you posted it, the place (area or station name), and part of the text (as close to the original as you can)
• If you had a mark: its name and approximate place

We delete only posts that match several of these details. To avoid deleting someone else's posts by mistake, if we cannot identify them we will not delete them, and may contact you at the reply address of the form to confirm.

4. For shops and facilities (requests to remove or correct a place or a must)

You can ask us to remove or correct a shop or facility shown in the App, or a note (a "must") left on it. Please write the following in the contact form below:

• That this is a "request from a shop or facility"
• The name of the place and roughly where it is (area name, part of the address, etc.)
• If your request is about a must, part of its text (as close to the original as you can)
• What you are asking for (removing a must / correcting the place's information (closed, moved, name, position) / removing the place, etc.) and why
• Something that shows your connection to the shop or facility (official website, phone number, etc. Even without it, we act on musts that clearly violate the Terms)

As a rule, we will acknowledge your request within 2 business days and tell you the outcome within 7 days. Anything that clearly violates the Terms or poses a danger is hidden on the day we receive the request. We may keep honest opinions and reviews that do not violate the Terms, even if removal is requested. Your contact details are used only to reply to you and are never added to the App's data. See section 7 of the Terms of Use for details.
