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 Export

Export a clean, timestamped log as a text file 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.

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.

📷 Photos stay on your device

In the current version, photos you attach are stored locally on your device only — they are not uploaded to our servers. Cloud photo sync is on the roadmap.

🗑 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.

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-to-text currently works best on Chrome/Android; on iPhone Safari, notes can be typed manually.

Do photos sync to the cloud?

Not yet in this version — photos stay on your device only. Text notes, timestamps, and GPS data sync automatically. Cloud photo sync is on the roadmap.

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.

Who built this?

Field Surveillance Log was built by Kevin Kubitskey, a licensed Arizona private investigator and retired Pima County Sheriff's Sergeant, based on real field surveillance work.
