"Sign out everywhere" revoked every other refresh token and nothing else. A native login is two rows, and the Bearer check consults only the paired access token, so the other phones kept working until that token expired, up to a day on the default policy. The route also handed destroyOtherSessions a session-kind credential for a Bearer caller, whose session.id is the ApiToken row id; the exception matched nothing and the calling phone revoked its own refresh token. destroyOtherSessions now finds the paired access tokens through the refresh rows and revokes them inside the same transaction, reporting the count, and the route names a Bearer caller by its access-token hash. Programmatic tokens are untouched. rotateRefreshToken marked the consumed row under usedAt: null alone, so a revocation landing between the read and the write was overtaken and a pair minted after the family ended stayed live. The guard now includes revokedAt: null; on a lost race the minted pair is retired and the reason distinguishes a revoked family from a double consume. withIdempotency consulted the grant only at replay time, and only for its existence; a narrow-scoped token was checked only on the delegated arm. Both move into the cell key: a delegated cell carries the grant's id, level and scope fingerprint, a narrow token's cells carry the token, and a request with no live grant neither reads nor claims a cell. Cookie and wildcard own-record cells are keyed byte-for-byte as before. Tests: integration for the paired access tokens (cookie and Bearer caller), a deterministic revoke-mid-rotation race against Postgres, unit coverage for the new cell keys, and the structural guard moved to the new invariant.

Why HealthLog
HealthLog is a self-hosted health tracking app (PWA + native iOS client) that runs from a single docker compose up on a NAS, homelab, or small VPS. It brings weight, blood pressure, pulse, blood glucose, body composition, sleep, mood, menstrual cycle, and medications onto one timeline — synced from the devices you already own — and keeps everything encrypted at rest on hardware you control. No vendor cloud, no subscription, no telemetry.
HealthLog is a personal health record-keeping and wellness tool. It is not a medical device and does not diagnose, treat, cure, or prevent any disease — it helps you log, visualise, and export your own data, and leaves clinical judgement to a clinician.

Highlights
- Every vital on one timeline. Weight, blood pressure, pulse, glucose, body composition, sleep, SpO₂, respiratory rate, mood, and cycle tracking — charted with trends, moving averages, and clinical reference ranges (ESH 2023, ADA 2024), overridable with the targets your clinician set.
- Clinical signals, opt-in and additive. Validated self-checks for mental wellbeing and sleep (WHO-5, PHQ-9, GAD-7, Sleep Condition Indicator — official questionnaire wording, calm crisis-resource handling), grip strength, a 0–10 pain score, waist and body measurements, and a longevity lab panel — each added through one signal registry, so a new signal wires into charts, correlations, the coach, the FHIR map, and the API at once.
- Records, structured. Allergies and family history as encrypted structured records that flow into the doctor report, plus lab values you key in or scan from a printed report — OCR extracts the stated values, units, and dates for you to review and confirm before anything is saved. HealthLog transcribes what a report says; it never interprets or diagnoses from it. (Immunization records are deliberately out of scope.)
- A document vault for the paper trail. An opt-in module stores every letter, report, and scan encrypted at rest — PDFs and photos preview inline, Office and text files stay download-only, and nothing user-uploaded can ever execute in the app. One searchable timeline with type, condition, and year filters, drag-and-drop and paste-to-upload, bulk filing, undo-able delete with a 30-day grace, and per-file/per-account limits the operator tunes.
- Context that explains the numbers. An opt-in environmental module folds weather, daylight, and temperature in as influence signals (winter darkness against mood, heat against blood pressure) using a home location you set, so a pattern has somewhere to point.
- Your devices, one server. Withings, WHOOP, Oura and Polar sync over OAuth2, Google Health connects Fitbit and Pixel Watch through your own Google Cloud client, Nightscout streams CGM glucose, an Apple Health
export.zipfolds your full history in, and the native iOS app streams HealthKit live. A per-metric source priority decides which reading is canonical when wearables overlap. - Medication tracking that tells the truth. Flexible schedules (weekly injections, weekday-only, intervals, PRN, cyclic), a configurable intake window per dose, and a traceable dose history where every slot reads taken, late, skipped, or missed — the same ledger the compliance rate is computed from, so the percentage can never disagree with the timeline.
- AI insights you own. Daily briefing, health scores, correlations, and a conversational coach grounded in your own measurements and interpreted against cited guideline reference bands — where a value sits and what that means in plain words, never a diagnosis. The coach proposes concrete if-then plans you accept or decline, and suppresses proactive check-ins when there's nothing genuine to say. Bring your own OpenAI or Anthropic key, or point at a local endpoint (Ollama, LM Studio, vLLM) so nothing leaves your network.
- Clinician-ready output. A doctor-report PDF generated client-side, a read-only HL7 FHIR R4 API, and scoped, time-limited share links you revoke after the visit.
- Private by construction. AES-256-GCM encryption at rest with zero-downtime key rotation, passkey login, server-side sessions, strict CSP — and no third-party tracking anywhere.
- Built to be lived in. Installable PWA with offline support, medication reminders over APNs, Telegram, ntfy, and Web Push, a sub-second dashboard on years of imported history — in English, German, Spanish, French, Italian, Polish, and Korean end to end.

Quick start (Docker Compose)
git clone https://github.com/MBombeck/HealthLog.git && cd HealthLog
cp .env.example .env
# Generate the three secrets (each a 64-char hex string = 32 bytes):
echo "POSTGRES_PASSWORD=$(openssl rand -hex 32)" >> .env
echo "ENCRYPTION_KEY=$(openssl rand -hex 32)" >> .env
echo "API_TOKEN_HMAC_KEY=$(openssl rand -hex 32)" >> .env
# LAN / plain-HTTP host (NAS, homelab, Tailscale) — required, or login fails:
echo "SESSION_COOKIE_SECURE=false" >> .env
docker compose up -d
Open http://localhost:3000 (or http://<host>:3000) — the first registered user becomes admin. The compose file pulls a pre-built multi-arch image (amd64 + arm64) from GHCR; no build step required.
Verify the running version:
curl -s http://localhost:3000/api/version # returns version + buildSha + builtAt
SESSION_COOKIE_SECURE=false is the one setting plain-HTTP self-hosts must set: without it the session cookie carries the Secure flag, the browser drops it over HTTP, and login silently fails. Leave it unset (or true) only when a TLS reverse proxy serves HTTPS — and then set NEXT_PUBLIC_APP_URL and APP_URL to the public URL first (see the self-hosting guide).
Persistent state lives in exactly one named volume (pgdata, the Postgres data dir); the app container is stateless, so backing up the database backs up everything.
NAS and homelab users have ready-made paths: Unraid Community Applications and Portainer app templates.
Self-hosting
One container hosts both the web server and the job worker by default; split them via HEALTHLOG_PROCESS_TYPE=web|worker for horizontal scale. Encrypted daily backups to any S3-compatible bucket are opt-in via the admin panel, new users join by invite link or QR code, and the stack works out of the box behind Caddy, Traefik, Nginx, or Coolify.
HealthLog ships releases roughly weekly. Pin a tag, back up before upgrades, and skim the CHANGELOG before pulling latest. The operator manual — reverse proxy, migrations, encryption-key rotation, backup and restore — lives at docs.healthlog.dev.
Native iOS app
A SwiftUI companion in public beta via TestFlight, built on the same API as the web client: live HealthKit two-way sync, medication reminders with action buttons that work without opening the app, and an on-device coach on Apple-Intelligence-capable iPhones. Code lives in MBombeck/healthlog-iOS.
Tech stack
Next.js 16 (App Router, React Server Components), TypeScript strict, PostgreSQL 16 with Prisma, pg-boss for jobs, Tailwind CSS 4 + shadcn/ui, Recharts, WebAuthn passkeys, Vitest + Playwright, multi-stage Alpine Docker image. The OpenAPI 3.1 contract for native clients is generated from the Zod schemas at docs/api/openapi.yaml.
