SELF Terms of Service

Last Updated: August 9, 2026
Version: 9.5.0

What SELF Is

SELF is your private and productive set of digital tools. Protected content is encrypted client-side before it reaches our servers. You hold the keys.

Progressive Web App (PWA)

SELF is available as a Progressive Web App. This means:

Installable - You can install SELF on your device like a native app
Offline capabilities - SELF can work offline for basic functions (planned feature)
Service workers - Live background processes for caching and notifications
Cross-platform - Works on desktop, mobile, and tablet devices
Browser install - You can install from your browser without app store restrictions

We Cannot Read What You Encrypt

SELF uses zero-knowledge encryption for specific protected content. Your device encrypts this content with keys we never receive:

AI conversation history and Memory Bank entries
Messenger content and attachments
Vault file contents, file metadata and folder names
Calendar event content
Mail sent between SELF accounts
Chain validator private keys

The server stores ciphertext for this protected content and does not hold the keys needed to decrypt it.

Information Needed to Run SELF

SELF can access limited service information, including your account email address, message routing identifiers and timing, calendar reminder times and event types, mail envelope data such as timestamp, size and folder, public wallet addresses, and billing or subscription status. Standard internet mail exchanged with external providers is readable while crossing the service boundary. Live AI prompts are processed on SELF-controlled EU GPU infrastructure to generate responses.

Your Data Stays Yours

We don't sell or mine your data - No advertisers, advertising profiles, or cross-site tracking
Client-side encryption - Named protected content is encrypted in your browser using the WebCrypto API (AES-256-GCM)
Recovery phrase-based encryption - Encryption keys are derived from your 12-word recovery phrase using BIP39
You can leave anytime - Export available data or delete your account anytime

You Can Always

Access your data - Export and decrypt supported protected content with your recovery phrase
Delete your account - Request deletion of your account and associated data under our retention rules
Export your data - Download supported account and protected content before leaving
Update information - Update your username or payment details anytime

We Can't And Won't

Try and access your messages or files
Track your browsing for advertising, or build cross-site profiles from your activity
Add SELF account identifiers to search requests - When you enable Connect-tier web search, search text is sent to a third-party provider without your SELF account ID, username, or email
Lock you into our service

What You Can't Do

To keep SELF safe for everyone, please don't:

Share illegal content or use SELF for anything unlawful
Try to hack or interfere with our service or other users
Spam or harass other users through messaging features
Resell access to your SELF account

Your Content

The protected content named above is encrypted with keys only you hold:

You own everything you create, upload, or store in SELF
You're responsible for ensuring you have rights to any content you add
Protected content stays private - the encrypted content named above remains unreadable to SELF
Keep it legal - don't store anything that violates laws

Intellectual Property

SELF software - We own the SELF application, interface, and core technology
Your content - You retain full ownership of everything you create using SELF
AI outputs - You own the results generated by customized SELF AI models within your Memory Bank
Open source - SELF uses open-source components under their respective licenses
No claims - We make no claims to your intellectual property or creative works

Security & Encryption

How We Protect Your Data

Client-side end-to-end encryption - Named protected content is encrypted in your browser using the WebCrypto API (AES-256-GCM) before transmission
Zero-knowledge architecture - The server stores encrypted blobs and cannot decrypt the protected content named above
Recovery phrase-based encryption keys - Encryption keys derived from your 12-word recovery phrase using BIP39 (mnemonic to seed)
TLS encryption in transit - Service traffic, including encrypted blobs, is protected by HTTPS during transmission
Stripe payment security - All payment processing uses Stripe's PCI-compliant encryption and security protocols
Both tiers - Zero and Connect tiers use identical client-side E2E encryption for maximum privacy
No server access to protected content - Server cannot read your AI conversation history, Memory Bank entries, messenger content, Vault content, calendar event content, SELF-to-SELF mail, or validator private keys

App Permissions

SELF requests only the permissions necessary for core functionality:

File system access - To save and sync your documents and data locally
Network access - To connect to your Memory Bank and sync data
Notification permissions - To alert you about important updates or security issues
Optional: Camera/microphone - Only when you choose to upload media or use voice features
Core functionality works - SELF operates fully even if you deny optional permissions

Authentication, Encryption and Recovery

Authentication and encryption use separate mechanisms. WebAuthn passkeys authenticate you to your SELF account. Your 12-word BIP39 recovery phrase derives your encryption keys on your device.

Primary authentication - WebAuthn passkeys provide secure, passwordless account access, with device support such as Face ID, Touch ID, or fingerprint recognition
Secondary authentication - Email and a single-use OTP provide a fallback sign-in path when a passkey is unavailable
Email privacy - We store a lookup-only email hash and a server-decryptable encrypted copy of your email for account access and operational communications. Plaintext email is not returned by APIs, and admin tools show a masked address.
Encryption key derivation - Your browser derives encryption keys from your recovery phrase using BIP39. Passkeys and OTPs do not derive those keys.
Optional recovery password - You may choose to store a server copy of your recovery phrase wrapped client-side with a password-derived key using 600,000 PBKDF2 iterations. SELF receives the wrapped blob and does not receive your password.
Multi-device access - The same recovery phrase derives the same encryption keys on each device
Recovery limits - A passkey or email OTP may restore account access without restoring access to encrypted content. Without the recovery phrase or the optional recovery-password path, encrypted content cannot be recovered by you or SELF.

Vulnerability Reporting

Found a security issue? We want to hear from you:

Security vulnerabilities - Report code and security issues to security@self.app (see Bug Bounty program). For all other inquiries use Settings → Contact Us
Responsible disclosure - We'll acknowledge reports within 48 hours and work with you on fixes
Security updates - Critical security patches are released immediately and pushed to all users
No penalties - Good faith security research is welcomed and protected

Third-Party Services

Memory Bank Definition

Your Memory Bank uses client-side end-to-end encryption on both tiers, with encrypted blobs stored in PostgreSQL on single-tenant bare metal infrastructure in the EU:

Both Tiers - AI conversations and Memory Bank entries are encrypted in your browser using the WebCrypto API (AES-256-GCM) before transmission. The server stores ciphertext and cannot decrypt it.
Data Export - Both tiers can export supported decrypted content through Settings. Decryption happens in your browser.
Recovery Options - Keep your recovery phrase secure. You may also enable the optional recovery-password feature, which stores a client-side wrapped phrase copy as described above. SELF cannot recover encrypted content without one of those paths.

Service Dependencies

Service availability depends on frontend CDN delivery, EU-based infrastructure providers, and Stripe billing
Performance may vary based on CDN delivery, single-tenant bare metal backend infrastructure, and dedicated EU GPU hardware conditions
Data sovereignty is maintained through zero-knowledge encryption, Memory Bank isolation, and EU-based single-tenant bare metal infrastructure
Payment security - Payments use Stripe's certified infrastructure
Frontend reliability depends on third-party CDN hosting of static assets (JS, CSS, HTML)
Backend reliability depends on EU-based single-tenant bare metal infrastructure
AI processing reliability depends on dedicated GPU infrastructure in EU data centers

Frontend Delivery (CDN)

SELF uses a third-party CDN for frontend hosting and global delivery of static assets (JS, CSS, HTML)
The CDN delivers public application files only. It does not receive your encrypted user content.
We are not responsible for CDN service interruptions or changes
CDN providers may change over time; these terms will be updated accordingly

EU Infrastructure

SELF backend API, database, encrypted Memory Bank, messaging, mail, and signaling run on single-tenant bare metal servers in the EU
Client-side encrypted Vault files, messenger attachments and SELF-to-SELF mail blobs use dedicated EU object storage (S3-compatible)
AI text and image processing uses dedicated (non-shared) GPU hardware in EU data centers
Infrastructure providers operate systems and do not receive the keys for client-side encrypted protected content
Providers may change over time; these terms will be updated accordingly
When your account is deactivated, associated storage is permanently deleted per our retention policy

Memory Bank Lifecycle

Your Memory Bank follows this lifecycle:

Creation - Storage is created when you first use SELF (available for both Zero and Connect tiers)
Isolation - Your storage is completely isolated from other users' data
Runtime - Storage holds your conversations and AI processes them securely
Encryption - Memory Bank conversations and entries are stored as client-side encrypted blobs on single-tenant bare metal infrastructure in the EU
Automatic deletion - Associated Memory Bank storage and content are permanently deleted when you deactivate your account
No recovery - Once deleted, storage data cannot be recovered

SELF App Validator Infrastructure

SELF App uses browser-based validators with backend chain coordination.
Browser validators participate in validation and consensus while backend orchestrator and coordinator services support rounds, chain state, availability, and prize draw coordination.
Validator private keys are derived from your recovery phrase, remain encrypted on your device, and are not provided to the coordination services.
Validator and prize draw participation may be temporarily unavailable if backend coordination services are interrupted.

AI Model Processing

SELF uses SELF AI models on dedicated GPU infrastructure in EU data centers
Live prompts are processed to generate responses; stored conversation history remains client-side encrypted in your Memory Bank
Memory Bank conversation history is stored as client-side encrypted blobs; the server cannot decrypt your content
No data sharing with model providers - Your conversations and AI interactions are not used to train third-party models
No model training - We do not use your conversations to train models
Model performance and availability depend on dedicated EU GPU infrastructure

Web Search Services (Connect Tier)

Availability - Connect tier only (including the 3-day free trial); not available on Zero
Search requests - Search text and URL retrieval requests are sent to a third-party provider without your SELF account ID, username, or email
Search results are provided "as-is" and we do not guarantee their accuracy or completeness.
We are not responsible for the content or accuracy of search results from third-party sources.
Service availability depends on third-party infrastructure and may be temporarily unavailable.

Search Service Limitations

Third-party dependency - Search services depend on external providers
No guarantees - We do not guarantee the accuracy, completeness, or reliability of search results
User responsibility - You are responsible for evaluating and verifying information from search services
Service interruptions - Search services may be unavailable due to third-party issues
No liability - We are not liable for decisions made based on search results
Content changes - Search provider behavior may change without notice

Stripe Payment Processing

SELF uses Stripe for secure payment processing and subscription management
During signup, we use Stripe's fraud detection (Stripe Radar) to verify payment methods
Stripe may analyze transaction patterns and geographic data for fraud prevention
We do not store IP addresses or payment details on our servers; IPs may be used briefly for login security
Your use of payment services is subject to Stripe's Terms of Service

Billing and Payments

Subscription Plans

SELF Zero (Free) - Memory Bank with client-side E2E encryption. 5 messages/day and seamless cross-device sync via recovery phrase (same phrase = same keys on all devices).
SELF Connect (USD $20/month via Stripe, 3-day free trial) - Memory Bank with client-side E2E encryption (same zero-knowledge security as Zero tier). Enhanced features include 100 messages/day, anonymous live web search, voice input, and AI personality customization.

Data Export and Recovery

Both Tiers - You can export supported decrypted content through Settings. Conversations and Memory Bank entries are decrypted in your browser and available for download in JSON format.
