Common troubleshooting

My data doesn't sync between devices

GutLedger is 100% on-device by design - there is no cloud sync, no account, no server-side copy of your data. Each install is independent.

To move your data to a new phone:

1. On the old phone, open Settings → Export data. You'll get a JSON file with every food log, symptom entry, Pro setting and trigger result.
2. Save the file to your cloud storage or email it to yourself.
3. On the new phone, install GutLedger and open Settings → Import data. Select the JSON file.

I paid for Pro but it didn't unlock

Pro is tied to the app-store account that made the purchase (Apple ID on iOS, Google account on Android):

1. Open GutLedger → Settings → GutLedger Pro → tap Restore purchase.
2. Make sure the App Store (iOS) or Play Store (Android) is signed in to the same account used for the purchase.
3. If the payment shows as pending, wait up to 24 hours - some card checks take time.
4. Still stuck? Email us with your store order number (Play Store orders start "GPA."; App Store receipts arrive from Apple) and we'll help unlock it.

The FODMAP elimination diet looks scary - where do I start?

Start with the Guided elimination in Pro. It walks you through:

1. Elimination phase (2-6 weeks): only low-FODMAP foods. GutLedger filters the food picker to safe items and tracks how your symptoms change.
2. Reintroduction phase: test one FODMAP group at a time (fructans, lactose, polyols, etc.) over 3 days each. GutLedger records reactions automatically and tells you which groups you tolerate.
3. Personalisation: settle into a long-term diet that only avoids the FODMAPs that actually trigger your symptoms.

The free tier has the FODMAP database (470+ foods) but not the guided protocol. If you're managing this yourself with a dietitian, Pro also exports a clean report you can share.

Trigger analysis says X is a trigger but I don't believe it

Trigger analysis correlates foods eaten in the previous 24-72 hours against symptom severity. It needs enough logged data to be meaningful:

• Minimum useful sample: 14 days of food + symptom logs.
• Confidence rating: each suggested trigger shows a confidence (low / medium / high) based on sample size and correlation strength. Treat "low" suggestions as worth retesting, not as a verdict.
• Confounders: stress, sleep and meds also drive symptoms. Log those too (Pro feature) so the analysis can account for them.
• If a suggestion clashes with your experience, you can mark a food safe or trigger manually from its detail screen and the analysis weights your input.

I want to delete everything

To completely remove your GutLedger data:

1. On device: uninstalling the app deletes the entire local SQLite database - all food logs, symptoms, settings and Pro data. No copy remains anywhere because there is no cloud backend.
2. Before deleting: if you want to keep the data for a doctor or future device, run Settings → Export data first.

The food I want isn't in the database

GutLedger ships with 470+ FODMAP-rated foods from the Monash University database and curated additions. If something is missing:

• Add it as a custom food (Food picker → + Add custom). Set your best-guess FODMAP rating; trigger analysis will refine over time based on your actual reactions.
• Email us the food name and we'll add it to the next release if we can find a reliable FODMAP rating for it.

Feature requests & feedback

GutLedger is built by one person, and every feature request is read. If you've got an idea that would make IBS management easier for you, I want to hear it.
