Signum Chat with AI HumanShield – Privacy Policy
Signum Chat with AI HumanShield™
Effective date: [CONFIRM-14]
Signum Chat is published by Dingane Innovations Inc. ("DII", "we", "us"), 3355 Lenox Road NE, Suite 750, Atlanta, GA 30326, USA. This policy explains what we collect when you use the Signum Chat app for iPhone and Android, why we collect it, who receives it and what you can do about it.
Your health information has its own policy, the Consumer Health Data Privacy Policy. Read both. If they differ on health information, the Consumer Health Data Privacy Policy applies.
In short
- You must be 18 or older.
- We collect what you give us (account details, chats, health entries, goals, copies of reports you choose to keep), what the app measures with your permission (steps, location, your voice) and basic technical data (crash reports, performance measurements and usage events).
- To answer you, Signum Chat sends what you write, and any files you attach to a chat, to third-party AI companies. You agree to this before you use AI features, and you can turn it off at any time.
- Your health entries are encrypted. You choose whether Chat and the Coach use them. NEW: A lab report or X-ray copy you save in My Health is kept for your doctor and is not read by AI.
- We do not sell your personal information, and we do not use it for advertising.
- You can export your data, withdraw your consents and delete your account in the app.

2. How we use it
- To run the app: sign you in, answer you, keep your chats, track your steps, keep your goals and health entries, keep the report copies you save, and manage your plan.
- To protect you: AI HumanShield™ checks every message, and every line of a voice call, for crisis language (Crisis Mode™) and for dehumanizing prompts (DIGNIFY™), labels who shaped each answer (PAIGE™ / HIVE MIND™) and keeps accountability records (TRACE™).
- To send what you asked for: reminders, progress updates and, if you opt in, text messages.
- To keep the service safe, fix failures, measure whether features work and meet our legal duties.
We do not use your conversations or health information to advertise to you, and we do not use analytics for advertising or ad measurement. We do not use your content to train an AI model, and we require our AI providers not to. [CONFIRM-3: confirm each provider's terms say so.]
3. AI and your information
Signum Chat uses third-party AI companies to create answers. Before any AI feature works, the app asks you to read the AI disclosure and agree.
- What is sent: what you write and any files you attach to a chat, and, if you have given health data consent on Pro or Exec, the My Health and My Goals details needed to answer your question.
- Who receives it: the providers named in the in-app disclosure: [CONFIRM-3: list each AI provider by name and what each does]. The in-app disclosure is read from our server, so it always names the current providers.
- NEW — Web Search and Deep Research. When you use Web Search or Deep Research (Deep Research is on Pro and Exec), the question you ask is sent to search providers, [CONFIRM-3: Tavily for Web Search and Perplexity for Deep Research, once the server keys are live; confirm the names, what each receives, and that no health details or personal identifiers are included]. The answer lists its sources as links. A link opens a website we do not run, which has its own privacy policy.
- NEW — Report copies are stored, not read by AI. Saving a lab report or X-ray copy authorizes storage only. We do not send it to any AI provider or other third party, and nothing in the app reads it with AI. If we ever offer a feature that does, it will run only when you make a specific request and give separate permission that tells you what will be shared and with which provider. Files you attach to a chat are different: they go to the AI provider so it can answer, as described above.
- Your choice: you can turn AI off at any time in Profile → AI and Chat Mode. Declining does not block Walk or any other feature that does not need AI.
- AI can be wrong. Answers are general information, not medical advice. See the Terms of Service.
Dr. Baruti AI Coach. The Coach is an AI representation of Dr. Baruti, made with his permission. It always says it is an AI. It is not Dr. Baruti, and it is not a physician you can reach. To produce its voice and video we use [CONFIRM-4: name the voice and video vendors and what each receives]. Questions you ask the Coach are processed the same way as Chat messages.
4. Who else receives your information
We share information only as follows.
| Who | Why | What |
|---|---|---|
| Apple and Google | To sell and renew your plan, and to deliver push notifications | Purchase status, notification tokens |
| Google (Firebase) | Crash reports, performance measurements, usage events and push delivery | Technical data, performance data, usage events, notification token |
| AI providers | To answer you (section 3) | As described in section 3 |
| NEW Search providers | To run Web Search and Deep Research | The question you ask [CONFIRM-3] |
| Voice and video vendors | To produce the Coach's voice and video and to run the voice call | NEW: during a voice call, your voice and the words of the call go to ElevenLabs, which runs the live call; [CONFIRM-4: confirm the vendor name, what it receives and what it keeps] |
| Text message provider | Only if you opt in to texts | Your mobile number and the message. Texts never include your health information. The provider is MSG91. |
| Email provider | Password reset links and account notices | Your email address and the message [CONFIRM-6: Hamza, name the email provider] |
| Google Maps | To show the map where you place your address pin | The map area you view |
| Authorities and advisers | When the law requires it, to protect people from serious harm, and to our professional advisers under confidentiality | Only what is needed |
| A buyer or successor | If DII is sold or merged | Your account information, under this policy |
We do not sell your personal information. We do not share it with advertising networks. Report copies are not shared with any provider other than our storage provider [CONFIRM-20: name the file-storage provider and where the files are held].
5. Voice and speech
- Dictation. When you dictate a message, your phone's own speech recognition turns your voice into text, and the text is sent as your message. Apple's or Google's speech service may process your audio under their own terms. We do not keep your audio. [CONFIRM-4]
- NEW — Talk hands-free (Pro and Exec). A voice call with the Dr. Baruti AI Coach uses your microphone for as long as the call lasts and sends your voice to our voice vendor so the Coach can reply as you speak. You start the call and you end it; the app tells you when the microphone is on. The call is AI, not a person, and it watches for crisis language the same way Chat does. If it detects one, it shows the Crisis Mode help buttons and stops. [CONFIRM-21: say whether audio, a transcript or both are kept, by us and by the vendor, for how long, and whether either is used to train a model.]
6. Location
- Signum Chat asks for your location in two places only: when you ask about places near you, after a screen that explains why, and when you tap to place your address pin in your profile.
- Permission is optional. If you decline, your message is still sent and Chat can ask you for a city or area instead.
- Walk never asks for your location. Steps and distance come from your phone's step counter.
- Location is used while you use the app, never in the background. [CONFIRM-7: say how long the position is kept, or that it is not stored.]
7. Notifications and text messages
- Push notifications and in-app reminders are on or off in Profile → Notifications and in your phone's settings.
- Push notifications and text messages never include your name, health values, medication names, conditions, report contents or Crisis Mode information. Their titles and previews are generic, for example "Your daily encouragement is ready. Open Signum Chat." (CEO decision, 1 Nov 2026).
- Text messages are sent only if you agree to them in Profile → Notifications → Text messages. They are limited to important updates and occasional encouragement, at most one or two every few days. Reply STOP to end them.
8. Analytics, performance and crash reports
We use Google Firebase for usage events, performance measurements and crash reports. Events record which screen you opened or which action you took. They carry no conversation text, no health values and no health area, and we record no event of any kind during Crisis Mode. Advertising features, ad personalisation and advertising ID collection are turned off. NEW: You can turn usage events and performance measurements off at any time in Profile → Privacy and security. [CONFIRM-22: Waheed, the switch is approved for 1.0 but not built yet; confirm the screen and wording once it is built.] Crash reports help us fix failures and are described in section 1. Firebase may also send a few automatic events of its own, such as the first time the app opens and when it updates.
9. Security
We encrypt your information in transit, and your conversations, memory, goals, health information and report copies at rest. [CONFIRM-12: confirm each category encrypted at rest, including backups and the stored files.] Report copies are opened only through short-lived private links, and the app removes location and camera details from pictures before keeping them. [CONFIRM-20: confirm.] Health information is not written to your iCloud or Android backup. Staff cannot open your My Health data except in a narrow, approved support role, where each access needs a stated reason and is recorded. No system is perfectly secure. If a breach affects your information, we will tell you and the authorities as the law requires.
10. How long we keep it
| Category | Kept for |
|---|---|
| Account, conversations, memory, goals, health information, walking history | Until you delete them or your account |
| NEW Report copies | While your account is open, unless you delete a copy sooner. Deleting a copy or your account removes your access to it immediately, and we permanently delete the file from active storage and backups within 30 days, unless a law requires us to keep it. [CONFIRM-20: Hamza to verify the system meets this, including thumbnails, before publishing] |
| NEW Voice call audio and transcripts | [CONFIRM-21] |
| NEW Search requests | [CONFIRM-7] |
| Payment and transaction records | As required for accounting, tax and audit. Your name and contact details are removed from them when you delete your account |
| Consent records | [CONFIRM-7] |
| Crisis Mode records | [CONFIRM-12] |
| Accountability (TRACE™) records | [CONFIRM-7] |
| Crash reports, performance data and usage events | [CONFIRM-7] |
| Answer reports and feedback | [CONFIRM-7] |
When the retention period ends, we delete the data or remove what identifies you. Deleted data may remain in encrypted backups for [CONFIRM-13] days.
11. Your choices and rights
In the app, under Profile:
- Export my data: we prepare a PDF copy of your information that you download in the app. The download link works for 15 minutes.
- Health data consent: give or withdraw it at any time. Withdrawing stops new health data being collected and stops its use in answers. [CONFIRM-13: confirm what happens to saved report copies when consent is withdrawn.]
- AI and Chat Mode: turn AI off at any time.
- Notifications and text messages: turn them off at any time.
- Memory and personalization: change or clear what the assistant remembers.
- Report copies: view or delete any copy at any time in My Labs, My Imaging Reports or Show My Doctor. [CONFIRM-20: the CEO's decision also says members can download each file; the app has view and delete only, so add download or drop the word.]
- Update profile: correct your details.
- Privacy and security: change your password and turn Face ID or fingerprint sign-in on or off.
- Delete account: deletes your profile, conversations, memory, goals, health information and report copies. See Account deletion. You can also email support@signumchat.ai. [CONFIRM-13]
Deleting your account does not cancel a plan bought through the App Store or Google Play. Cancel it in the store first.
If you live in California, Colorado, Connecticut, Virginia, Washington, Nevada or another state with a privacy law, you may have the right to know what we hold, to get a copy, to correct or delete it, to withdraw consent and to appeal a refusal. We do not sell personal information or share it for cross-context behavioral advertising, and we do not discriminate against you for using these rights. Send a request to support@signumchat.ai.
If you live in the European Economic Area, the United Kingdom or Switzerland, you have the right to access your information, to correct it, to delete it, to restrict or object to how we use it, to receive a copy in a portable format, to withdraw consent at any time, and to complain to your data protection authority. We use your information under these legal bases: to provide the service you asked for (your account, chats, goals and plan); your explicit consent (health information, AI features, text messages, location, microphone); our legitimate interest in keeping the service safe, fixing failures and measuring whether features work; and legal obligations. Health information is special category data, and we collect it only with your explicit consent. [CONFIRM-8: counsel to confirm the legal bases, the safeguard for sending information to the United States (such as standard contractual clauses), and whether DII must name a representative in the EU and UK. Do not publish worldwide availability until this is settled.]
12. Children
Signum Chat is for people 18 and older. We do not knowingly collect information from anyone younger. If you believe a child has an account, email support@signumchat.ai and we will delete it.
13. Where your information is processed
Signum Chat is available worldwide. We and our providers process information in the United States, wherever you live, and may process it in other countries where our providers operate. [CONFIRM-8: counsel to confirm the transfer safeguard named in section 11.] [CONFIRM-20: say where the production database and report files are held. The production server at api.signumchat.ai still uses the staging database; this must be settled before launch.]
14. Changes to this policy
We will post changes here with a new effective date. If a change affects health information or how AI uses your data, we will ask for your consent again where the law requires it.
