+## build & deploy
+
+### server (docker)
+
+```bash
+# build
+docker build -t synq-server ./server
+
+# run (replace paths and token as needed)
+docker run -d --name synq --restart=unless-stopped \
+  -p 8765:8765 \
+  -v /mnt/user/synq/data:/data \
+  synq-server
+```
+
+the server generates a random token on first start and logs it prominently. copy it into the android app settings. to use a fixed token instead, pass `-e PHONE_CAPTURE_TOKEN=yourtoken`.
+
+to rebuild after a `git pull`:
+
+```bash
+git pull
+docker build -t synq-server ./server
+docker stop synq && docker rm synq
+# re-run the docker run command above
+```
+
+### android
+
+open `android/` in Android Studio and hit **Sync**. then either:
+
+- **run on device/emulator directly** from Android Studio (▶), or
+- **build a release APK** from the terminal:
+
+```bash
+cd android
+./gradlew assembleRelease
+# output: app/build/outputs/apk/release/app-release-unsigned.apk
+```
+
+sideload to a connected device:
+
+```bash
+adb install app/build/outputs/apk/release/app-release-unsigned.apk
+```
+
+### releasing on gitea
+
+tag the commit and push the tag:
+
+```bash
+git tag v1.0.0
+git push gitea v1.0.0
+```
+
+then go to **Releases → New Release** in the Gitea UI, pick the tag, and drag the APK into the assets box. anyone on the LAN can download it from there.
+
+## backup
+
+### what to back up
+
+the server writes to one directory (the `/data` volume). back up the whole thing:
+
+```text
+/data/synq.org        ← the canonical org capture file
+/data/capture.sqlite3 ← idempotency store (dedup ids)
+/data/token.txt       ← auto-generated token (if not using PHONE_CAPTURE_TOKEN env var)
+```
+
+on unraid the host path is whatever you mapped in compose, e.g. `/mnt/user/ben/synq/phone-capture`.
+
+### restore behavior
+
+- restore the `/data` volume to a new container and start it. the server will pick up where it left off.
+- `synq.org` is append-only plain text — it is human-readable and recoverable even without the sqlite db.
+- if `capture.sqlite3` is lost but `synq.org` is intact, the server will accept re-posted captures that were already in the org file (no dedup). the android app marks them synced either way (`already_seen` or `accepted`), so the only side effect is duplicate org entries for anything re-synced. restore the db from backup to avoid this.
+- if `token.txt` is lost, delete it and let the server generate a new one on next start, then update the app settings.

+SynqApiClient in data/api/. OkHttp with 10s timeouts. checkHealth() does GET /health, returns false on any exception so callers never crash. postCapture() maps 401 → failed, non-2xx → failed, already_seen → AlreadySeen, else → Accepted.

+SynqSettings gained syncIntervalMinutes: Int = 15 field with DataStore key sync_interval_minutes. SettingsScreen added OutlinedTextField with number keyboard for interval, shows supporting text "WorkManager minimum is 15 min". buildSettings() coerces to max(value, 15). SettingsViewModel.save() now also calls SyncWorker.schedule(app, settings.syncIntervalMinutes). SyncWorker.schedule() uses REPLACE policy so new interval takes effect immediately.
