Privacy Policy
This policy covers apps published by Nilbit LLC, including Crumbs and the clinical reference apps (IV Drips, Paramedic Meds, IV Infusion Calculator, NurseCalcs, Hemodynamics, and Respiratory Meds). Questions: use Email us on the home page.
What the apps store
Crumbs saves game progress, hint counts, sound and haptic preferences, and which puzzle packs you have unlocked on the device. It does not require an account and does not collect a name, email, or location just to play.
Clinical apps save on-device data such as custom drugs, hidden items, notes, calculator preferences, and similar settings. They do not require an account to use core features.
Purchases
Optional purchases (for example hint packs, puzzle packs, or calculator unlocks) are sold through Google Play or the App Store. Those stores process payment. We receive a record that a product was bought so the app can unlock it. We do not see your full card number.
Support email
If you email us, we keep the message long enough to answer it. We do not sell that address.
Analytics and ads
Current Nilbit apps do not show ads and do not include a third-party analytics SDK.
Cloud save
A later update may sync progress with a cloud account so purchases and settings follow you to a new device. That would be optional and described in an update to this page before it ships.
Children
Crumbs is a general-audience word puzzle. It is not directed at children under 13. Clinical apps are intended for adult healthcare professionals.
Your choices
You can clear local data by uninstalling the app or clearing app storage in device settings. Store purchases remain tied to your Google Play or Apple account and can be restored on a new install.
Not medical advice
Clinical apps are reference and calculator tools only. They are not a substitute for professional judgment, facility policy, or current drug labeling.
Changes
If this policy changes in a material way, we will update the date at the top of this page.
