Privacy Policy

Last updated August 11, 2026 · Version 2026-08-11

In plain English

Juno is a daily news app that calls you with a personalized briefing written by AI.
We collect what you tell us (interests, prompt, schedule, name, email, phone) and what we generate for you (your briefings).
With your permission, DeepSeek is the primary writer for daily briefings, while OpenAI writes onboarding previews and serves as a fallback. Production audio is generated by Inworld; OpenAI and Lemonfox are available alternates. We do not send your phone number, email, password, or payment details to these providers.
You can delete your account from inside the Juno mobile app. That deletes all data we hold about you.
We don't sell your personal information. We don't use it for advertising. We don't share it with data brokers.

Who we are

This Privacy Policy describes how Juno AI ("Juno", "we", "us") collects, uses, and shares information about you when you use the Juno mobile app, the Juno website at junoai.app, and the related services (collectively, the "Service").

By using the Service you agree to this Policy and to our Terms of Service. If you do not agree, do not use the Service.

Information we collect

Information you provide

Account information. Your email address, your name (if you give one), and a password (or, if you sign in with Google, a Google-provided identifier and the basic profile fields Google returns).
Phone number. Used solely to place your daily briefing call. Stored on your profile in E.164 format.
Briefing preferences. Topics, goal, angle, tone, news habits, schedule (call time, days, IANA timezone), and the natural-language prompt that describes what you want to hear about.
Free-text inputs.Anything you type into the "always cover" or briefing-feedback fields. This is treated as user content and is sent to our AI providers to write your briefing.
Payment information. If you subscribe through the website, Stripe processes your card; we never see your card number. If you subscribe through the iOS app, Apple processes the purchase under your Apple ID; we receive a transaction identifier from Apple, not card details.

Information we generate for you

Briefings. The text and audio of each daily briefing we produce for you, plus the headlines, links, and summaries it cites.
Call records. The time, duration, outcome (answered, voicemail, no answer, etc.), and a reference to which briefing was delivered.
Saved articles. Articles you bookmark from a briefing.

Information collected automatically

Device and connection metadata. Standard server logs (IP address, user agent, timestamps) when you use our servers.
Web analytics (website only). The Juno marketing site uses PostHog to count page views and product events. PostHog identifies you by your Juno user ID once you sign in. The Juno mobile app does not include PostHog or any third-party analytics SDK.

Information we do not collect

Phone calls are one-way. Juno calls you and plays a pre-generated audio file. We do not record, transcribe, or analyze anything you say on the call.
Contacts.If you tap "Save Juno as a contact" on iOS, we write a contact card into your on-device address book. We do not upload your contacts to our servers.
Location. We do not request precise location. The IANA timezone you pick during onboarding is the only location-adjacent signal we collect.

How we use information

To create and deliver your daily briefings.
To place your scheduled phone calls and route them through our telephony provider.
To operate, maintain, and improve the Service.
To communicate with you about your account, billing, trial status, and post-call summaries.
To prevent abuse, including blocking repeated trial use after account deletion (we keep a one-way cryptographic fingerprint of your phone and email for 365 days after deletion specifically for this purpose; see Retention).
To comply with legal obligations.

We do not sell your personal information, we do not use it for cross-context behavioral advertising, and we do not provide it to data brokers.

AI providers and what we send them

Juno is an AI-powered product. With your permission, we send specific pieces of your data to AI providers to make it work. We have summarized the full breakdown — including model names — on our AI Disclosures page. The short version:

Provider	Why we use them	What we send
DeepSeek	Primary provider for article summarization, show planning, and voice script writing for daily briefings.	Topics, goal, angle, tone, schedule, "always cover" text, briefing feedback, article material, and resulting summaries and show plans, as applicable to the task.
OpenAI	Writes anonymous and web onboarding previews; provides the fallback for daily briefing writing and the default built-in web search. OpenAI is also an available text-to-speech provider.	Onboarding topics, preferences, and notes; the same task-specific data as DeepSeek when writing fallback is used; prompt-derived search queries; or the completed script and voice settings when OpenAI text-to-speech is configured.
Exa	Web search, when the Exa search path is configured instead of OpenAI's built-in search.	Search queries derived from your prompt. Exa returns titles, URLs, and snippets, which are then summarized by DeepSeek or, on fallback, OpenAI.
Inworld	Production text-to-speech provider, using Inworld TTS-2 Flash (`inworld-tts-2-flash`, voice Dennis) by default. Another Inworld model remains available when configured.	The completed script and voice / pacing configuration.
OpenAI TTS or Lemonfox	Available text-to-speech alternates selected by server configuration. OpenAI `gpt-4o-mini-tts` is the code default when `TTS_PROVIDER` is unset.	The completed script and voice / pacing configuration.

These providers act as our processors: they handle the data only to perform the service we requested and per their published policies. We do not authorize them to use your inputs to train their models. We never send your phone number, email address, password, or payment information to any AI provider.

Other service providers

Beyond the AI providers above, Juno relies on these vendors to operate:

Supabase. Authentication and database hosting. Stores your account, profile, briefings, call history, and saved articles.
Apple. Processes In-App Purchases when you subscribe through the iOS app and provides server-to-server subscription notifications.
Stripe. Processes subscription payments initiated through the website.
Twilio and Telnyx. Place the outbound voice calls that deliver your briefing. They receive your phone number, the call audio URL, and call metadata. They do not receive your prompt or briefing inputs.
Google.If you sign in with Google, Google's standard OAuth profile fields (email, name, avatar) are returned to us by Supabase Auth.
PostHog (website only). Product analytics on the marketing site; not present in the mobile app.
SMTP email. Post-call summaries and trial-ending notices are sent over our own SMTP server.
NewsAPI and X (Twitter) (optional). Article and trends sources used to seed your briefing. We send queries derived from your topics or configured keywords.

Data retention

Account data. Kept while your account exists. When you delete your account, your profile and all linked rows (briefings, items, feedback, saved articles, call records) are removed in a single database transaction.
Trial-abuse fingerprints. When you delete your account, we keep a one-way cryptographic fingerprint of your phone number and email for 365 days. This blocks the same identifier from claiming a second free trial. The fingerprint cannot be reversed back to your email or phone.
Operational logs. Standard server logs are retained for up to 90 days for debugging and abuse prevention.
AI provider retention. Each AI provider has its own retention policy. We do not control how long they keep payload data; we direct you to their published policies.

Your rights and choices

Revoke AI-provider consent. Turn off Settings → Share data with AI providers at any time. Juno will stop sending your briefing inputs to AI providers and cannot write new briefings until you allow sharing again.
Delete your account. In the Juno mobile app, go to Settings → Delete account. The deletion runs immediately and removes everything we hold about you.
Edit your data. Most preferences (call time, schedule, topics, prompt, phone number) are editable from Settings.
Stop the calls. Remove your phone number, turn off the days you do not want to be called, or delete your account.
Cancel your subscription. iOS subscriptions are managed under Settings → Apple ID → Subscriptions. Stripe subscriptions can be canceled from the customer portal linked from your Plan page on the website.
Access or export. Email privacy@junoai.app with your account email and we will provide a copy of your data within a reasonable time.
EU/UK/California rights. If you are in the EU, UK, or California, you may have additional rights under the GDPR, UK GDPR, or CCPA respectively (access, correction, deletion, portability, objection). Use the same email to exercise them.

Children

Juno is not intended for, and we do not knowingly collect personal information from, children under 13 (or under 16 in the EU). If you believe a child has provided us information, contact privacy@junoai.app and we will delete it.

International data transfers

Juno is operated from the United States and our service providers are primarily located in the United States and the European Union. If you use the Service from outside the United States, your data will be transferred to and processed in the United States and other countries where our providers operate. By using the Service you consent to this transfer.

Security

We use industry-standard practices to protect your information: TLS in transit, encrypted storage at rest with our database provider, scoped access keys, row-level security on user data, and timing-safe comparisons for credential checks. No system is perfectly secure; if we discover a breach affecting your information we will notify you as required by law.

Contact

Questions, requests, or complaints: email privacy@junoai.app.

Changes to this Policy

We will update this Policy when our practices change. The "Last updated" date at the top will reflect the most recent change. For material changes (for example, adding a new AI provider that materially changes what data we share), we will notify you in-app or by email.
