Where is my data kept?
On your phone, in a database encrypted with AES-256. No account is required. Optional AI interpretation sends selected food and symptom records with separate consent; subscriptions use RevenueCat and store services. Details in the Privacy Policy.
How do I move to a new phone?
On the old phone, go to Profile → Encrypted backup. Choose a passphrase and save the file to Files, iCloud Drive or anywhere else. On the new phone, open Bulgu and choose Restore from backup on the welcome screen, pick the file and enter the passphrase. Because the database key is tied to the device, the phone's own backup is not enough on its own; use the encrypted backup.
I forgot my backup passphrase.
Bulgu never stores the passphrase, so that backup cannot be opened. If you still have the old phone, create a new backup.
When do possible triggers appear?
Bulgu looks at meals 4–48 hours before your symptoms. A FODMAP group or food needs at least 5 exposed days and 5 meals, plus at least 5 comparison days without it. Until then, Experiments shows counters for what is still needed. When you have logged every meal of a day, switch on All my meals are recorded on Today, so the analysis does not count a day you simply did not finish logging as "didn't eat it".
A card says "possible trigger". Should I stop eating it?
The card is a statistical signal worth testing, not proof. A planned test decides: the protocol in Experiments guides you through leaving a group out for a while and then reintroducing it in rising portions. Ideally, plan diet changes with a dietitian.
How do I start the low-FODMAP protocol?
In Experiments, the first phase is a 14-day baseline: you log without changing your habits. Then you can start a 4–6 week elimination in standard or gentle mode.
How do I get a report for my doctor?
Profile → Doctor report (PDF). Pick the period and report language (English or Turkish); the PDF is made on your phone and the share sheet opens. The PDF is not encrypted.
How do I connect Apple Health or Health Connect?
Profile → Health data. The sleep, steps, water and weight types you allow appear next to your logs. On Android, if Health Connect is not installed, this screen takes you to its Google Play page.
How do I change the language?
Profile → Language: System, Türkçe or English.
How do I delete my data?
Profile → Delete all data, then tap again to confirm. Uninstalling the app also deletes everything. Because we hold no copy, deleted data cannot be recovered.
Do I need internet? Are there ads?
The diary and analysis work offline. Purchasing, restoring and subscription verification require internet access. There are no ads or tracking.
Which devices does it run on?
iPhone with iOS 16.4 or later, and Android phones with Android 8.0 or later.
