Capstone Foundry Privacy Policy
Effective date: November 4, 2026
Who we are: Capstone Foundry is operated by DairyForge LLC ("we", "us"). Questions about this policy or your data: support@capstonefoundry.helmian.cloud.
1. What this policy covers
Capstone Foundry is an AI assistant app: you talk or type to a "buddy" that remembers what you tell it, can create images and short videos, and can set reminders. This policy explains what information the app collects, why, who processes it for us, and the choices you have — including how to delete everything.
2. Information we collect
Account information. Your email address and a password. Passwords are stored only as a salted cryptographic hash (scrypt) — we cannot read your password, and it is never stored or sent in plain text.
Profile information. The display name, age band, and "about me" notes you (or a parent setting up the account) provide. The age band is used to apply the right safety settings.
Conversations. The text of your chats, transcripts of voice conversations, and the memories your buddy saves from them. This is the core of the product: the buddy's memory lives in our database so it can recall what you told it in later conversations.
Voice audio. When you use voice mode, your audio is sent to our speech provider to be transcribed and answered. Voice conversations produce stored text transcripts, like chats.
Creations. Prompts you give for images or videos, and the media generated from them, which is stored so you can view it in the app.
Safety settings. Whether Safety Mode is on, and the parent PIN — stored only as a salted cryptographic hash, never in plain text.
Optional provider keys. If you choose the Advanced option to use your own AI-provider API keys, those keys are stored encrypted and are used only to make calls to that provider on your behalf.
Usage records. Counts of how you use paid features (for example, number of messages, voice characters, images, video seconds) so we can meter your plan's monthly credit allowance fairly.
Purchase information. Your plan, subscription status, and billing period, which we receive from our billing processor. Payments are handled by Apple, Google, or Stripe through RevenueCat — we never see, receive, or store your card number.
Connected computers (Helmian Connect plan only). If you pair a computer, we store its label and pairing state so your buddy can reach it through our relay. Actions on your computer require your approval.
What we do NOT collect: your location, your contacts, your browsing history, health data, or advertising identifiers. The app contains no advertising and no third-party analytics or ad SDKs.
3. How we use information
Only to run the service: holding the conversation, remembering what you told your buddy, generating replies and media, applying safety settings and content moderation, metering your plan, processing your subscription state, and keeping the service secure. We do not sell your personal information. We do not use your information for advertising, and we do not track you across other companies' apps or websites.
4. Who processes information for us
Your content is processed by service providers only as needed to answer you:
- AI model providers (OpenAI, Anthropic, and Google — the "brains" you can choose between) receive your chat text to generate replies.
- ElevenLabs receives voice audio for speech and voice replies.
- OpenAI Moderation receives chat input and generated replies for safety content checks.
- Media generation providers (Replicate, Runway, and HeyGen) receive your image/video prompts to create media.
- RevenueCat processes subscription purchases with Apple, Google, and Stripe, and tells us your plan state.
- Hosting providers (Vercel, for the app and media storage, and Neon, for the database) store and serve the service.
These providers process information on our behalf to provide the service. We do not sell information to them or to anyone else.
5. Families and Safety Mode
Capstone Foundry is for a general audience. The account holder creates the account, holds the password, and controls Safety Mode. When Safety Mode is on, additional content guardrails apply and turning it off requires the parent PIN when one is set. Age bands in a profile are a parent's household setting used to apply the right safety level — they are not shared with third parties as advertising data.
6. How long we keep information
Your account information, conversations, memories, and creations are kept while your account exists, so your buddy can remember you. When you delete your account (Section 7), that information is erased from our service databases. Limited billing records — purchase event ids and plan history, without conversation content — may be retained after deletion where needed for accounting, tax, and dispute purposes.
7. Your choices and rights
- Access and correction: your profile is visible and editable in the app's account area.
- Delete your account: in the app, open your account area and choose "Delete my account". Deletion requires your password and typing DELETE to confirm, and permanently erases your profile, memories, conversations, saved keys, paired computers, and credit grants. Deleting your account does not cancel a subscription — cancel it in the App Store, Play Store, or Stripe to stop billing.
- Questions or requests (including requests a parent makes about their child's information): support@capstonefoundry.helmian.cloud.
8. Security
Passwords and PINs are stored as salted hashes; provider keys you supply are stored encrypted; traffic between the app and our services is encrypted (HTTPS). No system is perfectly secure, but we work to protect your information and limit access to it.
9. Changes to this policy
If we change this policy in a way that matters, we will update the effective date above and notify account holders by email and in the app before the change takes effect.
