Privacy Policy
Last updated: October 10, 2026
Diana is an app for manifestation, visualization and personal growth. What you tell Diana is personal, so this policy says plainly what we keep, why, who helps us, and how you stay in control. It applies to the Diana app for iPhone and Android and to dianamanifest.app.
Who we are
Diana is developed and operated by Luis Gustavo Rodrigues Alves, Brazil (“Diana”, “we”), the controller of your personal data. Contact: support@dianamanifest.app.
What we keep
| Data | Why |
|---|---|
| Your account: a private account identifier created when you first open the app; if you sign in with Apple or Google, the account identifier and email address they share with us (Apple lets you hide your email); otherwise, the email address you give in onboarding | To keep your data yours and safe, and to contact you about your account; news only if you opt in |
| Your profile: name, city, work, relationship, birthday or zodiac sign, gender, and — only if you choose to give it — your sexual orientation; “About me”, your routine, desires, goals, dreams, the life you want, the people in your world, what Diana should know and what she should never include | To write Future Selves that are about you, and to respect what you never want mentioned |
| Your manifestations, their Future Self stories and audio, and affirmations | The core of the app: creating, keeping and playing them |
| Your Daily Journal (gratitude, intention, promise, mood), wins, challenges, playlists, inspirations and where you stopped listening | To show your progress, keep your streak and bring you back where you left off |
| Your settings (language, time zone, reminders, voice, narration) and where you heard about Diana | To make the app work the way you set it |
| Feedback you send us | To improve Diana |
Your data is kept on your device and in Diana’s private cloud so nothing is lost. Only you can reach it: every record is tied to your account and protected so no one else can read or change it. Your profile photo stays on your device.
We do not show ads, we do not track you across apps or websites, and we never sell your data or share it for marketing. We don’t use analytics or advertising SDKs.
Who helps us (service providers)
- Supabase — hosts our database, file storage and accounts (United States).
- OpenAI — when you create a Future Self, the details of that manifestation and of your profile are sent to OpenAI to write the story and its affirmations. OpenAI processes them on our behalf; under its API terms it does not use them to train its models.
- ElevenLabs — the text of your Future Self is sent to ElevenLabs to create its audio in Diana’s voice, on our behalf.
- RevenueCat — manages subscriptions and purchases on our behalf: it receives your account identifier and your purchase history from Apple or Google, never your card details.
- Apple and Google — app distribution, Sign in with Apple and Sign in with Google (when you choose them), and subscription payments, under their own policies.
These providers may process data outside your country (mainly in the United States). We rely on their contractual safeguards for international transfers, as required by the LGPD (Brazil) and the GDPR (European Union).
Legal bases
We process your data to provide the service you ask for (performance of a contract), with your consent where the law requires it (for example, optional information such as sexual orientation, and news emails), and for our legitimate interest in keeping Diana secure and working. You can withdraw consent at any time.
How long we keep it
As long as your account exists. When you delete your account, your data is removed from our servers right away, and from backups within 30 days.
Your rights and your control
- Access and portability: Settings › Download my data gives you a copy of everything we keep, as a file.
- Correction: edit anything in your Profile at any time.
- Deletion: Settings › Delete Account erases your account from our servers and your device.
- You may also object to or restrict processing, ask what we hold, or complain to your data protection authority (in Brazil, the ANPD). Write to support@dianamanifest.app; we answer within 15 days.
Security
Data travels encrypted (HTTPS). Your session is stored in your device’s secure keychain. On our servers, each record is reachable only by its owner, files are private, and the keys to our providers stay on our servers, never in the app.
Children
Diana is meant for adults (18 and older) and is not directed at children. If you believe a child has given us data, write to us and we will delete it.
Changes
If this policy changes in a way that matters, we will tell you in the app before it takes effect. The date at the top shows the latest version.
