Privacy Policy

Our Commitment to Privacy

TechChatLab is fundamentally committed to protecting your privacy. We believe that users have absolute rights over their personal data, and we have architected our apps and website to reflect this commitment at the deepest level.

Core principle: All data created within TechChatLab apps is stored exclusively on your device, encrypted, and owned entirely by you. We are a team, not a data company. We do not collect, monetize, or sell user personal data. We do not operate servers that receive your app data. We do not track your behavior.

Data We Collect

TechChatLab Apps (Local Storage)

When you use a TechChatLab app, any data you create — notes, habit logs, financial records, mood entries, tracked metrics — is created on your device and stored exclusively on your device using encrypted local storage. TechChatLab does not receive, store, or access this data.

We do not collect:

• Personal app data (notes, entries, records, lists, etc.)
• Device identifiers (IDFA, Android Advertising ID, etc.) from our apps
• Behavioral usage analytics from within our apps
• Health data or fitness metrics
• Financial information or transaction history
• User accounts or login credentials
• Geolocation data

Exception: Our apps integrate third-party advertising SDKs (see "Third-Party Ad Networks" below). These SDKs may collect limited data for ad serving purposes, as detailed below.

Website (techchatlab.com)

When you visit our website, we collect minimal data:

• Cookies: Basic functionality cookies only (no tracking cookies)
• Web analytics: We do not use Google Analytics or similar tracking services
• Contact form data: If you submit our contact form, your message is prepared for email delivery but never sent to our servers
• Email subscriptions: We do not currently operate an email newsletter

Local-First Architecture

All TechChatLab apps are built on a local-first, serverless architecture. This means:

Component	Architecture	Your Data
Data Storage	100% Local (on-device)	Never leaves your device; encrypted at rest using AES-256
Accounts	None required	You don't need to provide identity; no account database exists
Servers	Zero backend infrastructure	No central server = no possible breach of your data on our end
Analytics	None	We don't track app usage, feature adoption, or user behavior
Cloud Backup	User-controlled only	Optional iCloud backups are encrypted by Apple; we have no access

Third-Party Ad Networks

Children's Privacy (COPPA & GDPR-K)

TechChatLab takes children's privacy very seriously and complies with COPPA (Children's Online Privacy Protection Act), GDPR Article 8 (for EU children), and equivalent regional regulations.

Age Thresholds

• United States: Children under 13 are protected under COPPA
• European Union (GDPR): Children under 16 require parental consent for data processing (though member states may lower this to 13)
• Other Jurisdictions: We comply with local age thresholds (e.g., 14 in some regions)

Children's Data Practices

For apps that may be used by children:

• No intentional collection from minors: We do not knowingly collect personal data from children under the applicable age threshold without parental consent
• Automatic compliance: When Apple's Age Signal API indicates a child, our apps automatically:
  • Disable personalized advertising
  • Disable targeted ad delivery
  • Limit ad network data collection to frequency capping and fraud prevention only
• No analytics tracking: We do not use behavioral analytics that would track children's app usage patterns
• No persistent identifiers: We do not use persistent device identifiers to track children across apps
• Parental access: Upon request, parents can verify what data (if any) is held, request deletion, or request that their child's data not be tracked

COPPA Compliance (United States)

For apps rated for or known to have child users:

• We do not require registration or user accounts from children
• We do not collect names, email addresses, or other personally identifiable information from children
• We do not use persistent identifiers for tracking children
• We have implemented Apple Age Signal API support to detect and protect child users
• Parents can contact us at privacy@techchatlab.com to request data deletion or opt-out from data collection

GDPR-K Compliance (European Children)

We comply with GDPR Article 8 requirements for children in the EU and EEA:

• For users under 16 (or lower age per member state), we obtain verifiable parental consent before processing personal data
• We maintain records of parental consent mechanisms
• We provide clear information to children (in age-appropriate language) about data collection

iOS Privacy Features

App Tracking Transparency (ATT)

All TechChatLab apps on iOS comply with Apple's App Tracking Transparency framework:

• ATT Prompt: Our apps present the system ATT permission prompt before requesting access to the Identifier for Advertisers (IDFA)
• User Choice: Users can grant or deny permission. We respect their choice completely
• No Workarounds: We do not attempt to track users who have denied ATT permission
• Age Detection: When Apple signals that a user is under 13, ATT prompts are automatically disabled, and personalized ads are blocked

Privacy Labels (App Store)

Our apps display accurate App Store privacy labels that disclose:

• Data collected by TechChatLab (typically minimal or none, depending on app)
• Data collected by third-party ad SDKs
• Data practices (tracking, linking to user identity, etc.)

App Privacy Report

iOS users can view which apps are attempting to access identifiers and can see permission status in iOS Settings → Privacy & Security → Analytics & Improvements.

Opt-Out of Personalized Ads

iOS users can disable personalized advertising globally:

• Open Settings → Privacy & Security → Apple Advertising
• Toggle "Personalized Ads" OFF
• This setting disables personalized ads across all apps, including ours

Android Data Safety

Data Deletion

Users can delete all data from a TechChatLab app in two ways:

• Select "Delete Advertising ID" or disable personalization
• This affects ad personalization across all apps
