The Agreement

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User", "you") and ZenDiary (also known as "My Diary: AI Journal with Lock"), developed and operated by Pulkit ("we", "us", "Platform").

By downloading, installing, or using ZenDiary, you acknowledge that you have read, understood, and agree to be bound by these Terms. If you do not agree to these Terms, please do not use the app.

Eligibility

You must be at least 13 years of age to use ZenDiary.

If you are under 18, you represent that your parent or legal guardian has reviewed and agreed to these Terms.

Availability

ZenDiary is available globally via the Apple App Store and Google Play Store.

Some features may vary by region due to local regulations.

Plain English Summary: By using ZenDiary, you're agreeing to these rules. You need to be at least 13 years old. If you're under 18, make sure a parent or guardian is okay with you using the app.

Your Content & Ownership

ZenDiary is designed as a private, personal space. Unlike social media platforms, your content is yours alone.

You Own Your Content

You retain full ownership of all content you create in ZenDiary, including:

  • Journal entries (text content)
  • Photos and images you attach
  • Mood data and tracking information
  • Stickers and decorations you add
  • Chat conversations with Zeni (our AI)

We claim no intellectual property rights over your personal content.

Limited License Grant

By using ZenDiary, you grant us a limited, non-exclusive license to:

  • Store your content locally on your device
  • Process your content through AI features (when you use them)
  • Backup your content to your personal cloud accounts (when enabled)
  • Display your content back to you within the app

This license exists solely to provide you the service and terminates when you delete your account.

Plain English Summary: Everything you create in ZenDiary belongs to you. We don't own your journals, photos, or thoughts. We only process your data to make the app work for you.

AI Features & Consent

Local storage and AI processing are different

ZenDiary is local-first for journal storage. When you use AI features, relevant journal content may be sent to an external AI service to generate a response, reflection, recommendation, summary, or analysis.

Zeni, AI Insights, mood detection, recommendations, and similar AI features work by processing relevant content through ZenDiary and one or more external AI services. The external AI service used may vary by feature, platform, region, model availability, or configuration.

AI Notice and Your Choice

The current app may not show a separate in-app AI notice before every AI feature. Our Privacy Policy and AI processing notice explain the current AI processing while we work on making the in-app notice clearer.

If you do not agree to AI processing, do not use Zeni, AI Insights, mood detection, recommendations, or other AI-powered features. You can continue using non-AI journaling features, and you can request account or data deletion by emailing hi@zendiary.in.

Read more here: AI processing and provider-policy information.

AI Features & Usage

Mood Detection

May process your entry text when you save to suggest an appropriate mood. The suggestion may be wrong and can depend on the AI model or settings used.

Zeni Chat Companion

May process your messages, recent chat history, mood context, and relevant journal snippets to generate a personalized response.

AI Insights & Analysis

May process recent entries or selected entries when you request themes, summaries, stress patterns, personal growth insights, book recommendations, or similar features.

Data Commitments and Limits

  • • We do not sell your journal content to advertisers.
  • • We do not use your personal journal content to train our own AI models.
  • • Where service controls are available, we aim to configure AI processing to limit retention and training use.
  • • We do not promise that external AI services never store, log, or retain content unless that is true under the applicable contract, service settings, and law.
  • • AI requests are transmitted using HTTPS/TLS or comparable secure transport.

AI Limitations

Please understand the limitations of AI:

  • • AI-generated content may be incomplete, inaccurate, biased, or inappropriate for your situation.
  • • Mood detection is an approximation and may not reflect your actual emotional state.
  • • The AI companion provides automated responses and cannot understand your full life context.
  • • AI analysis should support, not replace, your own judgment and self-reflection.

Mental Health Notice

ZenDiary is a journaling tool, not a medical device.

  • • Zeni is an AI companion, not a licensed therapist, counselor, doctor, or crisis service.
  • • AI-generated insights are for personal reflection only.
  • • Do not rely on AI features for mental health diagnosis or treatment.
  • • If you are experiencing mental health difficulties, please consult a qualified professional.
  • • In case of emergency, contact local emergency services immediately.

Backup & Data Storage

ZenDiary follows a "local-first" philosophy. Your journal data is stored on your device by default and is never automatically uploaded to our servers.

Local Storage (Default)

By default, all your data stays on your device:

  • Journal entries and photos stored in encrypted local database
  • Chat history stored locally
  • Settings and preferences stored locally

We cannot access this data. If you uninstall the app without backing up, this data is permanently lost.

Optional Cloud Backup

You may optionally enable backup to your personal cloud storage:

  • Google Drive: Backup stored in YOUR Google account
  • iCloud (iOS): Backup stored in YOUR Apple iCloud account

By enabling backup, you authorize ZenDiary to:

  • Create and update a backup file in your cloud storage
  • Read the backup file to restore your data

We cannot access your cloud backup. It is stored in your personal account.

Server-Side Data

We store minimal data on our servers (Firebase/Google Cloud):

  • Account information (email, name, profile picture)
  • Subscription status
  • Anonymous usage analytics

We do NOT store your journal content, photos, or chat history on our servers.

⚠️ Data Loss Warning: You are responsible for backing up your data. If your device is lost, stolen, or damaged, and you have not enabled cloud backup, your journal entries cannot be recovered.
