Your journal, your information.
Privacy notice ·
What we save
Neutrino saves your verified phone number, profile, messages, photos, videos, food and workout records, AI replies, explicit memories, and delivery information. Corrections keep both the original estimate and your updated value. We also retain technical records needed to process messages, limit abuse, and investigate failed deliveries.
How it is used
Your information powers your private journal and personalized coaching. The coach receives a limited selection of your profile, saved facts, recent records, and relevant attachments. It does not receive your entire message history on each request. Food estimates and video observations can be wrong.
Service providers
We use Supabase for accounts, databases, and private files; Vercel for the dashboard and webhooks; Railway for background processing; OpenAI for AI analysis; Twilio for phone verification and texts; and Cloudflare Turnstile for signup protection. These providers receive the information needed for their roles. SMS and MMS travel through Twilio and your carrier and are not end-to-end encrypted. Application connections use HTTPS; media access is restricted.
Training and sharing
Neutrino does not sell your journal or share phone numbers or messaging consent with third parties for their marketing. We do not automatically add your entries or corrections to a model-training dataset. A future training program would require a separate opt-in. OpenAI requests use its API with response storage disabled; provider abuse-monitoring retention may still apply.
Encryption and access
The dashboard and application-to-provider connections use HTTPS/TLS. Supabase encrypts database, private media storage, and backups at rest using provider-managed encryption. Service credentials stay on the server. Access checks limit records and media to their owner, and attachment links expire. SMS/MMS is not end-to-end encrypted: Twilio, carriers, and anyone with access to your phone may be able to read texts. Use the dashboard for information you do not want to send by SMS.
Modes, reminders, and safeguards
We save your Log/Coach selection, coaching style, reminder schedules, timezone, and delivery state. Automated text and image screening helps identify harmful requests and health concerns. Internal safety flags can be wrong; they are not diagnoses. Health concerns are handled separately from abuse signals and may pause proactive coaching. These flags and original messages remain private, with manual review available through the support form. We also save capped, aggregated security events using hashed network identifiers, without raw IP addresses or request contents.
Your choices
You can review your journal, change your profile, remove active coaching memories, and turn off texts or daily check-ins. Forgetting a memory stops its use as a saved fact; it does not erase the original journal entry. Send an account, export, or deletion request using the support form in Your profile. Requests are reviewed manually. Journals remain stored until removed; provider backups and required transaction records may persist under their retention policies. Abandoned uploads are scheduled for cleanup after one day.
Texting
Signing in sends a verification code. Journal replies, requested reminders, and coaching texts require separate consent in your profile. Reply STOP to stop these texts or HELP for help. STOP also cancels active reminders. Message frequency depends on your activity and requested schedules; daily coaching check-ins are optional and limited to one per day. Message and data rates may apply. See our Terms & texting policy.
