03 · data and privacy

03. What's stored, what never leaves

  • AccountNone. There is no sign-up and no login.
  • AnalyticsNone. No trackers, no telemetry, no ads.
  • Your logLives on your device. Nothing leaves it unless you turn on sync.
  • Jam by cameraReads the picture on this device and sends nothing anywhere.
  • Sync, when onWrites to a file in your own Google Drive. Your account, your file, your delete button.
  • StorageThe log lives in the browser's own storage on this device. Stills and diagrams live beside it in IndexedDB, as pixels, not uploads.
  • The Drive fileOne JSON file, smartlog-backup.json, in your own Google Drive: takes, production setup, stills and diagrams. Open it, download it, delete it whenever you like.
  • TokensYour Google sign-in token stays in the app's storage on this device. There is no SmartLog server for it to go to.
  • UninstallClearing the app clears the local log. Your Drive copy stays yours until you delete it.
  • The one tallyThe site counts downloads and launches as a single anonymous number, once per day per device, no identifier. That is the entire telemetry.

04. What comes out the other end

Everything SmartLog exports is a file the rest of the pipeline already understands.

  • Camera reportPDF · circled takes, contact sheets, lighting diagrams
  • Editor markersResolve, Premiere, Final Cut · slate, lens and notes on each marker
  • DIT handoffSilverstack-ready take data
  • Camera reportPDF, A4 landscape, columns auto-fitted to your field setup. Circled good takes, struck false takes, contact sheets, lighting diagram pages.
  • CSVYour columns, in your order, from the report designer. Round-trips back into SmartLog with nothing lost.
  • SilverstackA CSV shaped for Silverstack's own import, matching by timecode, clip and camera. Whole log or one shooting day at a time.
  • DaVinci ResolveA marker EDL. Timelines > Import > Timeline Markers from EDL. Circled takes arrive green, false takes red, each marker carrying slate, clip, lens, stop, filters and your note.
  • Premiere ProSequence markers as XML, importable straight from File > Import. The sequence starts at the hour your day started, so markers sit at the camera's own timecode.
  • Final Cut ProFCPXML with exact rational times, drop-frame aware. Circled takes arrive as completed to-dos, green; false takes red.
  • JSON backupThe full-fidelity copy: everything, including hidden fields, stills and diagrams.

07. Where it runs

  • iPhone / iPadInstalls from Safari via Add to Home Screen

  • The log and reportany phone, tablet or desktop browser from the last few years
  • Jam by cameraneeds camera access over a secure connection; most accurate on browsers that timestamp camera frames (iOS 15.4 and newer, Chrome 83 and newer). Where they do not, the app says so on screen.
  • LTC jamany device with a microphone input and an attenuated 3.5mm cable
  • InstallAdd to Home Screen from Safari or Chrome; it runs full screen and offline like any app
  • Bench honestyjam by camera is bench-proven against synthesised displays at 24, 25 and 30 fps; reports from your camera are welcome and credited

08 · the critical questions

08. Asked by people who know their gear

  • Can a teammate overwrite my work?No. Deletes never travel, adds merge, and your typed detail survives a sync. The log is deliberately hard to destroy from one phone.
  • Is the jam frame-accurate?By camera: inside a frame, and it prints its measured accuracy every time. By cable: frame-perfect.
  • No internet on set?Everything works offline. Sync catches up when you do; the QR handoff never needs internet at all.
  • Do my stills go to the cloud?Only if you turn sync on. They ride inside your own Drive file, nowhere else.
  • What is the catch?There is none to find: no account, no analytics, no paid tier. The only thing counted is an anonymous download tally.
  • Can I leave?Any time, with everything: CSV, JSON and PDF export are all one tap.
