Moodly

Privacy Policy

Moodly app and website · Last updated 18 October 2026

In short

  • Moodly has no account, no server, no analytics, no ads and no tracking.
  • Everything you enter in Moodly is stored only on your phone. We never receive it.
  • Data only leaves your phone when you decide so: an encrypted backup, a PDF you share, or a diagnostic report you email to us.
  • The website sets no cookies and loads nothing from third parties.

1. Who is responsible

The controller under the EU General Data Protection Regulation (GDPR) is:

Albert Nimtz (Knoxx Media)
Gliesmaroder Straße 93
38104 Braunschweig
Germany
Email: privacy@knoxx.media

Knoxx Media is run by a private person. It is not a company. We have not appointed a data protection officer, and the law does not require one.

2. The Moodly app

2.1 Data stored on your device

Moodly works without an account and without a server. Everything you enter is stored in a database inside the app on your phone. This includes:

Some of this is health data, which the GDPR treats as especially sensitive. We cannot see, read or receive any of it. It never goes to us or to anyone else, unless you send it yourself as described below. If you turn on the app lock, Moodly stores only a cryptographic hash of your PIN, in Android's secure storage. If you turn on automatic backup, Moodly also stores a key made from your backup password there, never the password itself (see 2.3). Since version 2.0.0 (build 46), Moodly does not take part in Android's automatic cloud backup or device-to-device transfer, so your data is not copied to your Google account or to a new phone. In older builds, Android may include the app data in your device backup to your Google account, if you have turned that on in Android.

Moodly also keeps a small technical log on your device (max. 512 KB) to help find errors. It stays on your device unless you send a diagnostic report (see 2.5).

2.2 Health Connect

If you turn this on, Moodly reads the following data from Android Health Connect: sleep, steps, exercise sessions, distance, total calories burned, and menstruation. Moodly shows sleep, steps, exercise and cycle data next to your moods. Distance and calories are only requested because the health integration needs them in order to work; Moodly does not display them. Moodly never writes data to Health Connect.

The imported data is stored only on your device. You can delete it in the app settings at any time, and you can withdraw the permission in the Health Connect settings at any time.

Moodly's use of information received from Health Connect will adhere to the Health Connect Permissions policy, including the Limited Use requirements. We do not sell this data, use it for advertising, or share it with anyone.

2.3 Optional backup to Dropbox or a file

You can create a backup of your data. Before saving, Moodly encrypts it on your phone with a password that you choose (AES-256-GCM). We do not know this password and cannot restore it.

The Dropbox provider is Dropbox International Unlimited Company (Ireland) or Dropbox, Inc. (USA), and data may be processed in the USA. Dropbox takes part in the EU-US Data Privacy Framework. Dropbox only receives the encrypted file and its file name and cannot read your entries. The Dropbox privacy policy applies to your Dropbox account: dropbox.com/privacy. Legal basis: your consent and your request (Art. 6(1)(a) and (b) and Art. 9(2)(a) GDPR).

2.4 PDF report

You can create a PDF summary, for example for your therapist. Before you create it, you choose what goes in. The PDF is not encrypted. You decide where to save it or whom to share it with, using Android's share dialog. We do not receive it.

2.5 Diagnostic report

If you want help with a problem, you can send us a diagnostic report by email. Moodly creates a text file and opens your email app; nothing is sent until you press send. The report contains: app version, device manufacturer and model, Android version, language, time zone, a random session ID, your app settings, a technical log, and the number of stored items. It does not contain your entries, notes or tag names. We use the report only to find and fix the problem, and delete it when the problem is solved. Legal basis: Art. 6(1)(b) and (f) GDPR.

2.6 Permissions

2.7 Deleting your data

You can delete single entries, and all cycle, self-harm or Health Connect data, in the app. To delete everything, uninstall Moodly or clear its storage in Android settings. Backups you created stay where you saved them. You can delete them in your file manager or in Dropbox. In Moodly you can also disconnect Dropbox.

3. The website

This policy also applies to our website at knoxx.media/moodly.

3.1 Server log files

When you open the website or download the app file, your browser automatically sends technical data to our hosting provider's server: IP address, date and time, the page or file requested, the amount of data transferred, the referrer URL, and your browser and operating system. This is necessary to deliver the website and keep it secure. The hosting provider processes this data on our behalf under a data processing agreement. Log files are deleted after a short time, unless they are needed to investigate an attack. Legal basis: Art. 6(1)(f) GDPR.

3.2 No cookies, no tracking

The website does not use cookies, analytics or tracking. Fonts and all other files come from our own server. If you choose a language or a light/dark theme, your browser saves this choice locally (keys moodly_lang and moodly_theme). This is never sent to us, and you can delete it at any time in your browser settings. This storage is strictly necessary for a function you asked for (§ 25(2) no. 2 TDDDG).

4. When you contact us

If you write to us by email (for example privacy@knoxx.media or moodly@knoxx.media), we use your email address and message only to answer you. We delete them when the matter is finished, unless the law requires us to keep them longer. Legal basis: Art. 6(1)(b) and (f) GDPR.

The app and the website link to other websites, for example Ko-fi (donations), crisis helplines and the Health Connect page in the Google Play Store. These links open in your browser or in another app. Those services are responsible for their own data processing. Moodly does not send them any of your data.

6. Age

Moodly is intended for people aged 18 and older. Because we receive no data from the app, we cannot know who uses it.

7. Your rights

Under the GDPR you have the right to:

To use these rights, email privacy@knoxx.media. Please note: we have no data from the app. You control that data yourself on your device.

You also have the right to complain to a data protection authority. The authority responsible for us is:

Die Landesbeauftragte für den Datenschutz Niedersachsen
Prinzenstraße 5, 30159 Hannover, Germany
lfd.niedersachsen.de

8. Changes to this policy

We update this policy when the app or the website changes. The date at the top shows the current version.
