Privacy policy

Last updated · August 8, 2026

Important notice to users outside the U.S.

This service is operated in the United States. If you are located outside of the United States, please be aware that any information you provide to us will be transferred to the United States. By providing us with any information through the Site or the Services, you consent to this transfer.

1. Introduction

Moodlog, LLC ("we," "our," or "us") operates moodlog. We know you care about how your information is used and shared, and we take your privacy seriously. Please read the following to learn more about our Privacy Policy (the "Policy"). By using or accessing our website moodlog.io and any of our related applications that we currently offer or may offer, launch, acquire, or make available in the future, in any manner, you acknowledge that you accept the practices and requirements outlined in the Policy, and you hereby consent that we will collect, use, and share your information in the following ways.

We may update the Policy at any time. The date of the last modification will be posted at the beginning of the Policy, and we may provide notice on our site or by email that the policy has changed. By continuing to use and access the website and applications, you agree to any modifications to the Policy.

2. Information we collect

We collect the following types of information about you:

· Account information: When you create an account, we collect your email address, username, and password (stored encrypted).

· Journal content: We store the journal entries you create, including text content and associated emotion tags. This is the core functionality of the service. Your journal entries must comply with moodlog's Terms of Service.

· Communications content: We may receive feedback or other communications from you via moodlog or external services such as email.

· Payment information: We do not collect or process payment information. The service is free during the research preview.

· Automatically collected information: We collect some information automatically as you use our Service, including usage data: information about how you interact with the service, including login times, feature usage, and session activity.

3. How we use your information

We use the information we collect for the following purposes:

· To operate the application, including creating and maintaining your account, plus enabling you to create and store journal entries.

· To analyze the content of your entries to identify emotional patterns and generate personalized insights about your mood via AI and natural language processing (NLP) technology. This occurs each time you submit an entry.

· To send you communications related to your account, such as account verification, password resets, and service updates.

· To understand how moodlog is used to identify areas for improvement, and to develop new features.

· With your explicit consent, for research purposes. We will never use your information for research without first obtaining your affirmative consent, and you may withdraw that consent at any time. Personal data used for research is anonymized.

Before we use your data for a purpose that is materially different than the purpose we collected it for or that you later authorized, we will provide you with the opportunity to opt out.

4. Data sharing and disclosure

We do not sell your personal information. However, we may share your information in these limited circumstances:

· We share information with third-party vendors who perform services on our behalf, such as hosting services. These service providers are authorized to use your information only as necessary and are obligated to protect your information.

· We may disclose your information if required by law, regulation, or governmental request, or where we believe in good faith that disclosure is necessary to protect the rights, property, or safety of our users, the public, or moodlog.

· Your information may be shared and transferred in the event of a business acquisition or merger. We will notify you by email and in the service if there is a change in the privacy policy in the event that this occurs.

· We reserve the right to disclose any information provided to or collected by our Services that we believe is necessary or appropriate to comply with the law, any court order, subpoena, or other legal process, or to enforce or apply our Terms of Service.

· With your explicit consent, we may disclose information for research or other purposes.

5. Data security

We implement reasonable and appropriate technical and organizational security measures to protect your data from loss, misuse, unauthorized access, disclosure, alteration, or destruction, including encryption, secure authentication, and regular security assessments. However, no method of transmission over the internet is 100% secure.

Your journal entries are encrypted at rest. moodlog operates the servers and holds the encryption keys, which means moodlog can access the contents of your entries to provide features such as insights and pattern detection, and, only if you opt in, to include anonymized entries in research. moodlog is not end-to-end encrypted: your entries are protected against theft of the database or disk, but they are not hidden from moodlog itself. Individual entries are never shown to other users.

6. Data retention

We retain your data as long as your account is active. When you delete your account, we will delete your personal data within 30 days, except where we are required to retain it for legal purposes.

7. Your rights

You have the right to access your personal information, export your data, and delete your account and data at any time using the settings page. You may also adjust research data sharing preferences and communications preferences at any point while using moodlog.

8. Age of users

The service is not targeted to or intended for people under 18 years of age. If you are under 18, you may not use moodlog, access the website or provide any content. We do not knowingly collect information from children under 13.

9. Changes to this policy

We may update this privacy policy from time to time. Changes to our privacy policy will be posted on this page. We will notify you of significant changes to how we treat users' personal information via email or through a notice on the website. The date the privacy policy was last revised is noted at the beginning of this policy. You are responsible for ensuring we have an up-to-date active and deliverable email address for you.
