At Oneira, we take your privacy seriously. This Privacy Policy explains how we collect, use, and protect your personal information when you use our dream journal application.
We collect information you provide directly: account information (email, name), dream entries and content, mood selections, and app preferences. We also collect usage data: app interactions, feature usage statistics, and device information for troubleshooting.
We use your information to: provide and improve our services, personalize your experience, generate dream statistics and insights, send important notifications about your account, and develop new features based on usage patterns.
Your data is securely stored on encrypted servers. Dream content is stored privately and is only accessible by you. We use industry-standard security measures to protect your information from unauthorized access.
We do not sell your personal information. We may share data with: service providers who assist in operating our app (under strict confidentiality agreements), and legal authorities when required by law.
We implement appropriate technical and organizational measures to protect your data, including encryption in transit and at rest, regular security audits, and access controls. However, no method of transmission over the internet is 100% secure.
Oneira offers an optional security feature called NightLock that provides end-to-end encryption for your dream entries. When you enable NightLock, you create a personal 6-digit PIN that is used to generate a unique encryption key. This key encrypts all your dream content (text, mood selections, tags, and AI analyses) before it leaves your device.
Your NightLock PIN is never stored on our servers in any form — not as plain text, not as a hash, and not in any recoverable format. We use a zero-knowledge architecture, which means that only you can decrypt your dreams. Even Oneira staff cannot access your encrypted dream content.
The encryption process works as follows: your 6-digit PIN is combined with a unique salt value tied to your account to derive a strong cryptographic key using industry-standard key derivation. This derived key is then used to encrypt and decrypt your dream data using AES-256 encryption.
Because we never store your PIN, it is impossible for us to recover your data if you forget your PIN. There is no "forgot PIN" option, no recovery email, and no backdoor. If you lose your PIN and switch to a new device, your previously encrypted dreams will be permanently inaccessible. We strongly recommend that you write down your NightLock PIN and store it in a safe place.
You can change your NightLock PIN at any time from the Profile menu. When you change your PIN, all your existing dreams are re-encrypted with the new key. This process happens entirely on your device.
Important: Your NightLock PIN cannot be recovered by Oneira under any circumstances. If you forget your PIN and need to access your dreams on a new device, your encrypted data will be permanently lost. Please store your PIN securely.
You have the right to: access your personal data, correct inaccurate data, delete your account and data, export your dream entries, and opt out of marketing communications. Contact us to exercise these rights.
We use the following third-party services to operate and improve our app: Supabase (authentication and cloud database), RevenueCat (subscription and payment management), OpenAI API (AI-powered dream analysis), Apple Speech Framework (on-device voice-to-text conversion). These services may process certain data on our behalf under strict privacy and security agreements. We encourage you to review their respective privacy policies.
