Most business apps require you to hand over your data to their servers in exchange for features. LawnBook is built differently. Everything — your clients, jobs, invoices, expenses, and financial records — lives on your device. This guide explains exactly how data storage, backup, export, and AI privacy work.
The Four Privacy Pillars
Local-First Architecture
LawnBook stores all data using Apple's SwiftData framework, which writes to your device's local storage. There are no Srisan Labs servers that receive or hold your business data. When you add a client, schedule a job, or log an expense, that data goes directly to your device's storage — not to any cloud database.
This has two practical implications. First, LawnBook works completely offline. You can use every feature including AI tools with zero internet connection. Second, Srisan Labs cannot access your data, ever. There is no back-end database to breach, no support team with access to your records, and no way for us to look at your client or financial information.
Practical implication: If you forget your iPhone passcode, your data is protected by the same encryption Apple applies to all local storage. LawnBook cannot help you recover it — because we don't have it. This is a feature, not a limitation.
iCloud Backup and Sync
LawnBook supports optional iCloud backup and device sync through Apple's CloudKit framework. When enabled, your data is encrypted and stored in your personal iCloud account — not on Srisan Labs infrastructure.
iCloud sync serves two purposes:
- Backup — If you lose or replace your device, restoring from iCloud restores all your LawnBook data
- Cross-device sync — If you use LawnBook on both iPhone and iPad, data stays in sync across both devices through iCloud
iCloud backup is off by default. Enable it in Settings → iCloud → Enable iCloud Backup. You need an Apple ID and sufficient iCloud storage for your data size (most users' LawnBook data is well under 1GB).
Tip: Enable iCloud backup immediately after setting up LawnBook. Data loss from a lost or broken phone is the most common support request we receive, and it's entirely preventable with iCloud backup turned on.
Data Export: CSV and PDF
You own your data and can export all of it at any time from Settings → Export Data. Available export formats:
- Full CSV export — Every client, job, invoice, expense, and mileage record in spreadsheet format, importable into Excel, Google Sheets, or any business software
- PDF reports — Formatted reports for clients, expenses, invoices, and tax documents
- Accountant package — Bundled ZIP file with Schedule C report, P&L statement, expense detail, and mileage log (also available from Tax Center)
Exports are generated on-device and shared via the iOS Share Sheet. Send to email, AirDrop, Files app, or any other app on your device.
On-Device AI: What This Actually Means
Every AI feature in LawnBook — the lawn assistant chat, voice job entry, receipt scanning, photo analysis, smart estimates, proposal generation, and anomaly detection — runs using Apple's Core ML framework on your device's Neural Engine.
When you use any of these features:
- No data is sent to any server to process the request
- No photos, receipts, voice recordings, or business data leave your device
- The AI model is embedded in the app and runs locally, like any other app feature
- An internet connection is not required for AI features to work
This is technically different from apps that say "AI-powered" but actually send your data to OpenAI, Google, or their own servers for processing. LawnBook's AI is genuinely local.
What Data LawnBook Does Not Collect
To be specific about what does not happen:
- No analytics SDK (no Mixpanel, Amplitude, Firebase Analytics, or similar)
- No crash reporting that uploads data to external servers
- No advertising identifiers or tracking pixels
- No behavioral data collection
- No email marketing (beyond purchase receipt from Apple)
- No user profiling of any kind
The only external service LawnBook uses is Apple's App Store for purchases and Apple's CloudKit for optional iCloud sync. Both are governed by Apple's privacy policies, which are among the strongest in the industry.
Privacy Model Summary
If you prefer a simple model: think of LawnBook like a notebook app. The notebook app stores things on your phone. The notebook company can't read your notes. LawnBook works the same way — it's a local-storage app that stores your business data on your device, accessed only by you.
The only difference from a simple notebook is that iCloud backup optionally copies that data to your private iCloud storage, and AI features use a model embedded in the app itself. Both mechanisms keep your data under your control.
Deleting Your Data
Deleting the LawnBook app from your device removes all locally stored data. If iCloud backup is enabled, delete LawnBook data from iCloud separately via iPhone Settings → Apple ID → iCloud → Manage Account Storage → LawnBook. Because Srisan Labs holds no data on our own servers, there is no account to delete and no server-side data to request removal of.
