Senvrilo privacy policy
Last updated: 30 September 2026
Senvrilo is published by Qubzylthar Nexus LLC ("we", "us"). This policy explains what the Senvrilo mobile application does with your information.
This document has not been reviewed by a lawyer. It is an accurate description of what the software does, written from the source code, and it is a starting point for legal review rather than a substitute for it. It must be checked against the law where you operate before you publish it.
The short version
Senvrilo has no account, no server of its own and no analytics. Everything you enter stays on your device. We cannot see your jobs, your customers, your prices or your earnings, because none of it is ever sent to us.
Two things do leave your device, and neither contains anything you entered: a report when the app crashes, and a check for a newer version of the app.
What we collect
Nothing you enter. Your business details, customers, jobs, prices and payments never leave your device unless you send them yourself, as described below. We do not collect, receive, store, sell or share any of it, and we do not collect usage data.
We do not use analytics, advertising, cookies, device fingerprinting or tracking of any kind. The app does not ask for any device permission: no camera, no location, no contacts, no microphone, no notifications.
The app makes two kinds of network request, both to companies that provide a service to us and handle the data on our behalf.
Crash reports
When the app crashes or runs into an error, it sends a report to Sentry (Functional Software, Inc.), which collects crash reports for us so we can find and fix the problem. A report contains:
- what went wrong: the error, and where in the app's code it happened
- the app's version, and which update of it was running
- your device's model, operating system version, language and time zone, and
technical details such as free memory and storage
- a short trail of what the app did just before, such as a button being
pressed or the app moving to the background; this names parts of the app, not anything you typed or saved
- possibly a random identifier created when the app was installed, which tells
us whether several reports came from one installation; it is not linked to you or to your device's advertising identifier, and reinstalling the app replaces it
A report does not include your name, your email address or your IP address, and the app does not attach anything you entered to it. The app tells Sentry not to record IP addresses, and it does not send personal information, screen recordings or screenshots. A launch where nothing goes wrong sends Sentry nothing. Reports travel over an encrypted connection, and Sentry deletes them automatically at the end of its retention period.
Checking for updates
When you open the app, it asks Expo (650 Industries, Inc.), which delivers updates to the app, whether a newer version of the app's code is available, and downloads it if there is one. The request carries the app's version and update channel, your device's operating system, and a random token that Expo uses to count how many installations have received an update. It does not identify you and contains nothing you entered.
Like any connection over the internet, both requests reveal your IP address to the service receiving them. Sentry is told not to store it; Expo describes its own handling in its privacy policy at https://expo.dev/privacy. Sentry's is at https://sentry.io/privacy/.
What the app stores, and where
Everything you enter is written to your device's own app storage and nowhere else. That includes:
- your business details, such as name, address, phone, email, payment terms and
tax rate
- customer names and any contact details you choose to add
- jobs, quotes, contracts, visits, costs, prices and notes
- payments you record, including their date, amount and method
This data belongs to you and sits under your control. It is removed when you delete the app or clear its data.
When information leaves your device
Anything you entered leaves your device only when you deliberately send it, and only to a destination you pick:
- Sending a document. When you produce a quote, invoice or receipt, the app
creates the file on your device and hands it to your phone's own share sheet, or to your browser's print dialog on the web. You choose where it goes. The file is not uploaded anywhere first, and it does not pass through us.
- Exporting a backup. The backup is a file created on your device and handed
to the same share sheet. Where it ends up, such as your email, a messaging app or cloud storage, is your choice, and that destination's own privacy policy then applies to it.
We receive nothing in either case.
Security, stated plainly
App storage on a phone is protected by your device's own security, which means your passcode, biometric lock and the operating system's app sandboxing. **The data is not separately encrypted by the app.** Anyone who can unlock your device and open the app can read what is in it.
Because there is no cloud copy, losing or wiping your device loses the data with it. Export a backup if the information matters to you, and keep that backup somewhere safe, because it is plain, unencrypted text.
Children
Senvrilo is a business tool for adults and is not directed at children. The only information we receive is the crash reports described above, which do not identify anyone, so we do not knowingly collect personal information from anyone, children included.
Your rights and your choices
We hold none of the information you enter, so there is nothing of it for us to disclose, correct, export or delete on your behalf. You already hold every copy:
- See it: it is all visible in the app.
- Correct it: edit or delete any job, customer, visit or payment.
- Export it: use the backup export in Settings.
- Delete it: delete a job from its own screen, or remove the app to erase
everything at once.
Crash reports do not identify you, so we have no way to pick out the ones that came from your device. If you have a question about them, or about anything else here, write to us at the address below.
This covers the rights the GDPR, the UK GDPR and the CCPA give you. We have never sold or shared personal information, and we have no mechanism to do so.
Changes to this policy
If a future version of Senvrilo adds accounts, cloud sync, backups on our servers or anything else that sends data off your device, this policy will be updated before that version ships, and the app will tell you what changed. The date at the top of this page always reflects the current version.
