Field Surveillance Log by Tharsis Investigations LLC
Built by a licensed investigator, for licensed investigators

Court-Ready Surveillance Logs, Built From the Field — Not a Notepad

GPS-timestamped entries, voice-to-text notes, and secure cloud sync — so your documentation holds up when it matters, without slowing you down on the job.

Works on phone, tablet, or desktop. No software to install.

Paper logs and text-message notes don't hold up.

Every investigator has been there: scribbled notes in a truck, a timestamp you're reconstructing from memory, a photo buried in your camera roll with no record of when or where it was taken.

When opposing counsel challenges your documentation, "I'm pretty sure it was around 2pm" isn't good enough. Field Surveillance Log exists to close that gap.

  • Handwritten logs get lost, damaged, or challenged for accuracy
  • Texting yourself notes leaves no verifiable timestamp or location
  • Reconstructing a timeline after the fact invites cross-examination
  • Nothing syncs — one lost phone means one lost case file

Everything you need in the field, nothing you don't

Built around how surveillance work actually happens — not a bloated case management suite.

📍

GPS-Timestamped Entries

Every log entry captures date, time, and location automatically — no manual reconstruction later.

🎙

Voice-to-Text Notes

Dictate notes hands-free from the vehicle. No typing while you're trying to stay on a subject.

🔒

Private Cloud Sync

Entries sync to your own private account — visible only to you, backed up if you lose or replace your device.

📁

Organized by Case

Log entries under a case name or file number so everything stays sorted and easy to pull for a report.

⬇

One-Click Report

Print or save a clean, timestamped log as a PDF to drop straight into your case report.

📱

Access Anywhere

Runs in the browser on your phone, tablet, or laptop. No app store, no install, no update to manage.

🎥

Photo, Video & Voice Memos

Attach photos, video clips, and voice memos to any entry. Each one is saved with the entry and synced to your private account.

🕒

Date, Time & GPS Photo Stamp

Burn the date, time, GPS coordinates, and case name right onto your photos before they are saved.

🚗

Subject & Vehicle Profile

Keep the subject's description and vehicle details with the case, printed at the top of your report.

🛣

Mileage & Hours

Log miles and hours for each case so billing and expense reports are ready when the job is done.

Security & Data Handling

You're putting case notes, GPS data, and client-related information into this platform. Here's exactly how it's handled.

🔒 Private, per-user accounts

Data is stored with Row Level Security enforced at the database level — your account can only ever access your own entries. No shared visibility between users.

🚫 Never sold, never used for advertising

Case notes, timestamps, and location data are not sold to third parties and are never used to target ads. Full stop.

💳 Billing handled by Stripe

Payments are processed directly by Stripe. We never see or store your full card number — only limited billing status needed to manage your subscription.

📷 Private attachment storage

Photos, video clips, and voice memos upload to your own private storage. Only you can see them.

🗑 Delete your data anytime

Request full account and data deletion at any time by emailing us — verified requests are honored within a reasonable timeframe.

🏗 Infrastructure

Built on Supabase (authentication and data storage) and Netlify (hosting), with Stripe for billing — established providers, not a homegrown backend.

Full details in our Privacy Policy and Terms of Service.

Frequently asked questions

Is my data private?

Yes. Entries are stored in your own private account, protected so only you can see your own data. See the Security & Data Handling section above for details.

Does it work on iPhone and Android?

Yes, it runs in your phone's browser — no app store download required. Voice memos work on iPhone (Safari) and Android (Chrome). If your browser doesn't support live voice-to-text, type the note or record a voice memo instead.

Do photos sync to the cloud?

Yes. Photos, video clips, and voice memos upload to your own private cloud storage along with your notes, timestamps, and GPS data.

Can I cancel anytime?

Yes, there's no contract. Cancel in one click from inside the app, or email us — either way you won't be billed for the next period.
