Privacy Policy

Last updated: April 15, 2026

Imaginelle Labs ("we", "us", "our") operates the Sayvour mobile application ("App"). This Privacy Policy explains what information we collect, how we use it, and your choices regarding your data.

We believe in transparency and minimal data collection. Sayvour is designed to keep your food diary on your device. We do not require user accounts, and we do not sell your data to third parties.

1. Information We Collect

1.1 Data Stored Locally on Your Device

The following data is stored only on your device and is never sent to our servers:

• Food diary entries: Meal names, descriptions, portion estimates, nutrition information, and timestamps for entries you log
• Nutrition data: Calorie, macro, and micronutrient estimates computed from your logged meals
• App settings: Your preferences such as daily nutrition goals, units, and notification times

This data remains entirely on your device and is not transmitted to or accessible by us.

1.2 Data Processed When You Use Voice Logging

When you use the voice logging feature, limited data is sent to external services:

• Voice Input: Your audio recording is sent to our AI processing service for transcription and nutrition estimation. It is processed in real-time and not stored after processing.
• Meal description text: The transcribed text of your spoken meal description is sent to an LLM (large language model) service to infer meal content and nutritional information. This text is not stored after the response is returned.

1.3 Google Drive Backup (Optional)

If you choose to back up your food diary to Google Drive:

• Google account: You will need to sign in with your Google account. We do not create or store a separate user account.
• Backup data: Your food diary database is uploaded to your personal Google Drive and remains there until you delete it. We do not maintain copies on our servers.
• We use a limited Google Drive scope that restricts our access to only files created by Sayvour. We cannot read other files in your Drive.

This feature is entirely optional. The App functions fully without it.

1.4 In-App Purchases

If the App offers paid features, purchase transaction data is processed by Apple or Google and their payment processing partners to verify and manage your purchase status. We do not directly handle or store payment information.

1.5 Data We Do NOT Collect

• We do not collect your name, email address, or phone number
• We do not track your location
• We do not use analytics or advertising tracking SDKs
• We do not collect device identifiers for advertising purposes
• We do not read your contacts, photos, or other personal files
• We do not store your voice recordings or food diary data on our servers

2. How We Use Your Information

We use the limited data we process to:

• Provide voice logging: Converting your spoken meal description into a food diary entry with estimated nutrition information
• Enable cloud backup: Saving and restoring your food diary to your personal Google Drive (only when you initiate it)
• Manage purchases: Verifying your purchase status for any paid features
• Prevent abuse: Rate-limiting voice processing requests to maintain service quality

3. Third-Party Services

The App uses the following third-party services, each governed by their own privacy policies:

• AI / Voice Processing Provider — Transcribes your voice input and infers meal content and nutritional information. Audio and text are processed in real-time and not retained.
• Google — Google Drive and Google Sign-In for optional backup and restore. Privacy Policy
• Apple / Google — Process in-app purchase transactions where applicable. Subject to their respective privacy policies.

4. Permissions

The App requests the following device permissions:

• Microphone: To record your voice when you initiate a voice log. Audio is only captured when you tap the record button. The App does not record audio in the background.
• Notifications: To send optional meal reminders or daily summary notifications at your preferred time. You can disable this in your device settings at any time.
• Internet: Required for voice processing, Google Drive backup, and purchase verification.

All permissions are optional. Core features of the App may still function without them, though voice logging will not be available without microphone access.

5. Data Storage and Security

• Local storage: Your food diary is stored in a local database on your device, protected by your device's built-in security (screen lock, device encryption).
• Data in transit: All network communication uses HTTPS encryption.
• Voice data: Audio sent for processing is transmitted over HTTPS and is not stored after the response is returned.
• Google Drive backups: Protected by your Google account security. We use a limited Drive scope that restricts access to only files created by Sayvour.

6. Data Retention

• Local data: Retained on your device until you delete it within the App or uninstall the App.
• Voice recordings: Not retained. Processed in real-time and immediately discarded.
• Google Drive backups: Retained in your Google Drive until you delete them. We do not maintain copies.
• Purchase records: Managed by Apple and Google per their retention policies.

7. Your Rights and Choices

You have full control over your data:

• Access: All your food diary data is visible within the App at all times.
• Delete: You can delete individual entries, or all data, at any time within the App. Uninstalling the App removes all locally stored data.
• Permissions: You can revoke any permission at any time through your device settings.
• Backup control: You choose whether to enable Google Drive backup. You can delete backups from your Google Drive at any time and revoke the App's access via your Google account settings.
• Notifications: You can disable notifications at any time through your device settings or within the App.

8. International Data Transfers

When you use the voice logging feature, your audio data may be processed on servers located in the United States. By using this feature, you consent to this transfer for the purpose of processing. The data is not stored after processing.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by updating the "Last updated" date at the top of this page. We encourage you to review this page periodically.
