Training: *"We do not use your + inputs or outputs to train any AI models or request prompt or response content in support + requests."* Storage, specifically for cloud-hosted models: *"When using cloud-hosted + models, we process this content transiently to provide the Service and this content is not + stored beyond the time required to fulfill the request,"* and separately: *"We implement + technical measures designed to minimize retention of prompt and response content."* (The + same section separately confirms fully local/on-device Ollama usage involves no data + collection at all — not the mode used here, since Utilitool calls the hosted Ollama Cloud + API.) +- Neither provider's policy calls out image data as a distinct category from text + prompts/outputs — both quoted commitments (training and storage) are stated generically + over "Inputs and Outputs" / "prompt and response content," which covers the base64 image + payloads sent for OCR under the same terms as text, but neither page explicitly says so. +- OCR results are **suggestions only** — nothing is auto-saved. The extracted value is + returned to the client and only persisted if a staff member reviews and resubmits it + through the normal create endpoints (`POST /readings`, `POST /billing-cycles`), which + apply the existing anomaly (5×) and consumption-tolerance (3%/5%) checks regardless of + whether the value came from OCR or manual entry. +- Utility-bill photos may contain more personal/financial detail (account holder name, + address, account number, amount due) than a bare meter-reading photo, which typically + shows only the meter face and numeric display. +- Before any image is sent to the vision provider, the server re-encodes it + (`api/functions/src/lib/image-fetch.util.ts`, via `sharp`) to strip EXIF metadata — + including GPS location tags a phone camera may embed — while baking in the correct visual + orientation first, so the stripped image still displays right-side up. +- API keys for Groq/Ollama are supplied by the requesting user, encrypted at rest + (AES-256-GCM, `src/lib/crypto.lib.ts`), and are never returned in any API response. +- **Recommended**: enable Groq's **Zero Data Retention** option (Data Controls settings, + see ["Your Data in GroqCloud"](https://console.groq.com/docs/your-data)) on the Groq + account used for OCR/chat. This is a setting on the requesting user's own Groq account — + Utilitool cannot enable it on their behalf — but doing so removes even the limited + (up to 30 days) abuse/reliability-log retention window described above, which is the + lowest-risk posture available for both the organization and the tenants whose data is + processed. + +## Data Isolation + +Utilitool does not implement per-landlord/per-tenant data partitioning — all authenticated +staff accounts (any role) can see the full shared property/reading/billing dataset for the +organization. This is an intentional architectural decision (single organization, multiple +staff users), not a per-customer SaaS boundary. There is no cross-organization data sharing +since there is only one organization's data in a given deployment. + +## Insight Chatbot + +The chatbot (`POST /chatbot`) is restricted to the `admin` role (`landlord`/`assistant` +accounts receive `403`) — this narrows the data-to-third-party exposure below to only the +admin's own requests, rather than every staff member's. The web `ChatWidget` is hidden +entirely for non-admin users to match; there is no mobile chatbot UI. Chat history is not +persisted server-side — the client resends prior turns on each request. + +Within that admin-only scope, the chatbot answers questions using the same shared dataset +any staff member already has read access to via the normal UI — it does not introduce new +data exposure beyond what the requesting admin's role already permits. + +- To answer a question, the chatbot calls internal tool functions + (`api/functions/src/features/chatbot/chatbot.tools.ts`) that read readings, consumption + totals, and billing costs, then sends those results to the same requesting user's + configured Groq/Ollama Cloud provider (the same providers and data-handling terms + described above for OCR) so the model can compose a natural-language answer. +- Property/unit identifiers (`Property.room_name`) are replaced with an opaque per-request + token (e.g. "Property 1") before any tool result is sent to the provider + (`chatbot.service.ts`'s `createPropertyNameMasker`), and only mapped back to the real + name in the final reply shown to the user. The provider never receives the real + property/unit name. No tenant names or addresses are ever included — the chatbot's tools + never query the tenant repository. +- Consumption totals and computed peso billing costs are sent as-is, since they are the + analytical output the chatbot exists to produce; the same Groq/Ollama no-training, + limited/no-retention terms quoted above apply to this data. + +## Retention & Deletion + +- Records use soft deletion (`is_deleted` flag) by default via `DELETE /:id`. This is the + normal, low-friction deletion path for day-to-day use, and is reversible via + `PATCH /:id/restore`. See `api/CLAUDE.md` → "HTTP Method Semantics". +- **Permanent deletion (purge)**: for right-to-erasure requests — e.g. a tenant asking for + their data to be permanently removed — every entity also supports a second, irreversible + step: `DELETE /:id/purge`. This only works on a record already soft-deleted (`409` if it's + still active) and is restricted to the `admin` role. Meter-group, property, and reading + purges cascade to their already-archived readings/billings, mirroring the existing + archive cascade, so a purge cannot leave orphaned records behind. See `api/CLAUDE.md` → + "Archive-Then-Purge Lifecycle". +- Meter-reading photos are only stored if the photo-settings preference is explicitly + enabled per user; bill/billing-cycle photos are never stored. +- This document does not set a fixed data-retention period — retention is governed by + operational need and, if the organization is subject to a specific data protection + regime (e.g. the Philippine Data Privacy Act), by that regime's requirements. The + archive-then-purge lifecycle gives staff a concrete mechanism to act on an erasure + request once one is received, rather than only a soft-delete that leaves data recoverable + indefinitely. diff --git a/api/firestore.indexes.json b/api/firestore.indexes.json index 4184a26..f7487a6 100644 --- a/api/firestore.indexes.json +++ b/api/firestore.indexes.json @@ -4,263 +4,195 @@ "collectionGroup": "billing_cycles", "queryScope": "COLLECTION", "fields": [ -
