Privacy Policy
Effective date: May 24, 2026
Who we are: nitre ("nitre," "we," "us") — Spencer Ray Janelle, California, USA.
Contact: privacy@nitreapp.com
nitre reads the residue of your day and gives you a nightly "era" card. This policy explains what we collect, how we use it, and the choices you have. The short version: you don't make an account to use nitre, we don't sell your data, we don't run ads or third-party tracking, and the raw media you give us is read once and deleted — never used to train models.
What we collect
- A guest ID. When you first open nitre, the app generates a random ID and stores it on your device. It is not your name, email, or phone number. It lets your history (your "drift") accumulate across nights. There is no email/password sign-up to use nitre.
- The residue you choose to give us, per night. Any mix of: a typed text thread, a screenshot or photo you pick, a song, a 10-second voice note, a one-thing-you-did, and a mood. You choose what to share each night; nothing is required.
- Derived "reads" we keep. From your residue we generate and store a privacy-stripped internal read of the night plus your resulting era (its name, one-liner, rarity %, mood, and date). See "Media: process-and-discard" below for what we do not keep.
- Basic technical data needed to run the service (e.g., a request IP used transiently for rate-limiting / abuse prevention). We do not build advertising profiles.
We do not collect: your name, email, phone number, contacts, precise location, or device advertising identifiers. nitre contains no third-party advertising or analytics tracking SDKs.
Media: process-and-discard (no training on your data)
When you give nitre an image or voice input, the raw file is uploaded to a private store, read once by our pipeline into a PII-stripped derived read, and the raw file is deleted in the same request. An hourly sweep deletes any orphaned upload as a backstop. We keep only the derived read, never the raw screenshot/photo/audio. Your inputs are never used to train any AI model. Voice notes are transcribed on your device — the raw audio never leaves your phone.
How we use what we collect
- To generate your nightly era card and your drift/wave history.
- To compute an honest rarity stat for the night.
- To operate, secure, and rate-limit the service (abuse / cost-bomb prevention).
We do not sell or rent your data, and we do not share it for advertising.
Who processes data for us (sub-processors)
- Supabase — database, storage, and serverless functions (hosting your guest data + derived reads).
- Anthropic (Claude API) — generates the read from your residue. Inputs sent to the commercial API are not used for training per Anthropic's commercial terms.
- Expo / EAS — app build and delivery infrastructure.
Each processes data only to provide its service to nitre.
Retention & deletion
- Your derived reads/eras are kept so your history accumulates, until you delete them.
- Raw media is never retained (deleted same-request; orphans swept hourly).
- Delete everything: the app's "delete everything" removes your user record and all your eras. This is irreversible. After deletion the device returns to a clean-slate guest.
Children
nitre is rated 17+ and is not directed to children under 13; we do not knowingly collect data from them. If you believe a child has used nitre, contact us and we will delete the data.
Your choices & rights
- Use nitre without an account (guest only).
- Choose what residue to share each night (or share nothing but a mood).
- Delete all your data at any time in-app.
- Depending on where you live (e.g., EEA/UK/California), you may have rights to access, correct, or delete your data and to object to certain processing. Contact us at privacy@nitreapp.com to exercise them.
Security
Media uploads use a private store reachable only by our server-side pipeline; the on-device guest ID is held in the device keychain. No method is perfectly secure, but we process-and-discard raw inputs to minimize what could ever be exposed.
Changes
We may update this policy; we'll change the effective date and, for material changes, surface notice in the app or at this URL. If we add optional paid features in the future, we'll update this policy to describe any related data (e.g., subscription status from Apple).
