Privacy Policy
Last Updated: January 13, 2026
By using this website (getsintera.com) or our application (app.getsintera.com), you consent to this Privacy Policy, as well as those of our subprocessors. For the rules that govern use of the service, see our Terms of Service. If you have any questions, you can catch us at help@getsintera.com.
tl;dr (Too Long; Didn’t Read)
Your privacy is our business model. We do not trade your information. As an independent company (Whole Life, LLC), our only allegiance is to our members, not to external investors or advertisers. This independence empowers us to prioritize ethics and safeguard your private thoughts above all else.
Encryption: Your writing is fully encrypted at rest and in transit (TLS 1.2 or greater).
AI & Privacy: “End-to-end encryption” (where the server sees nothing) is technically impossible to use with AI at the moment, as the AI systems need to process the text to generate insights. However, your data is NOT used to train or improve the public AI models we use.
The “Sintera” Patterns: We use a specialized graph database (Neo4j Aura) to find hidden patterns in your journey. Crucially, we do not store your raw journal entries there. We only store derivatives—abstract patterns, mathematical vectors, and encrypted insights—obtained via AI. This allows us to connect the dots without storing your raw secrets in the graph.
Data Hosting: All your core data is securely hosted on Google Cloud Firestore (US).
You own your data. You can export your data or delete your account at any time.
Analytics: We use PostHog to understand how people use our public website and our app. On the marketing site this may include analytics cookies, heatmaps, and session recordings with text masking enabled. We never share your journal content with PostHog.
Payments & Messaging: We use Customer.io for messaging. We use RevenueCat to manage subscriptions and Stripe to process payments securely.
We strive to collect the minimum amount of information required to operate our services.
1. Introduction
Whole Life, LLC (website: getsintera.com & app: app.getsintera.com) appreciates your trust. We are a Delaware-based company creating products and services focused on self-reflection and mental clarity. Please read and consent to this Privacy Policy to use our services.
2. Data Collection & Infrastructure
2.1 Data Storage (Core)
Our application runs on Google Cloud Functions and all user data is stored in Google Firestore.
Location: United States.
Security: Google Cloud adheres to ISO 27001, SOC 2, and other industry standards. Your data is encrypted at rest and in transit.
2.2 Pattern Recognition (Neo4j Aura)
To power the “Sintera” feature (finding patterns in your life), we use Neo4j Aura directly.
Privacy Guard: We do not store your raw journal text or personal narratives in Neo4j.
Derivatives Only: We only store derived information (abstracted data points and encrypted vectors) obtained via AI. These derivatives are always obscured or encrypted to ensure that the database contains only mathematical relationships, not your readable story.
2.3 Artificial Intelligence (AI)
To provide feedback, chat, and insights, we utilize third-party AI providers via their secure APIs. We currently use:
- OpenAI
- Google Gemini
- xAI Grok
Privacy Commitment: We access these services via their API tiers where data usage for model training is disabled. Your content remains private to your session and is not used to make the AI “smarter” for the general public.
2.4 Analytics
We use PostHog to track interactions across our public website and our application. On the marketing site, PostHog may also capture analytics cookies, heatmaps, and session recordings so we can understand which parts of the site help or hurt conversion.
Note: No sensitive data (e.g., journaling content, freeform reflection text, or insights) is shared with or processed by PostHog. Recordings and heatmaps are intended for the public website, not private journaling surfaces.
2.5 Messaging
We use Customer.io to manage our transactional emails (e.g., password resets) and product updates. We store your email address securely here.
2.6 Payments
We use Stripe as our payment processor and RevenueCat to manage subscription entitlements.
Security: We do not store your credit card information directly on our servers. All financial transactions are processed securely by Stripe (PCI-DSS compliant), the Apple App Store, or the Google Play Store. You can find Stripe’s privacy policy at
.
3. Use of Personal Data
We use your personal information in the following cases:
Verification/identification of the user during website usage.
- Providing technical assistance and customer support.
Sending updates to our users with important information.
Generating AI insights and visualizing patterns (via Neo4j) to make your experience personal.
Guaranteeing overall performance and administrative functions run smoothly.
4. Data Retention & Deletion
Retention: We retain your data as long as your account is active to provide the service.
Deletion: You may delete your account at any time via the app settings. Upon deletion, your raw data in Firestore is permanently removed, and your derived nodes in Neo4j are deleted.
