Privacy policy
SignOn Ready · Last updated 5 October 2026
In short. SignOn Ready has no accounts, no adverts and no tracking. Your documents, scans and records stay on your phone. What you type into the Rules finder is answered on your phone and is never sent to us. The app contacts our service only to check for updated rules.
Who we are
SignOn Ready is an app for seafarers and sea-career students, made and run by its developer, Capt. Charles ("we"). This policy explains what the app does with your information.
What stays on your phone
Everything you add is stored in the app's private storage on your phone and is not uploaded to us:
- your profile (name, rank, nationality, ship types, and any CV details you choose to enter);
- your documents: scans, photos, thumbnails, numbers and dates, and old versions;
- sea service, family documents, rest hours, drill dates, PSC ticks, exam progress and settings;
- your app-lock PIN, kept only as a scrambled (salted hash) value, never the PIN itself.
Reading a scanned document (Auto-read) is done on the phone. The app may fetch a reading component from a public software library host the first time; no part of your document is sent.
What is sent to our service
| When | What is sent |
|---|---|
| You buy, restore or check Pro (when purchases are on) | A random purchase ID and the purchase receipt, sent to RevenueCat and Google Play. |
| The app checks for updates (about weekly) | A request for the latest rules, library and PSC data. Nothing about you is included. |
Searching the rules. The Rules finder works on your phone, with no internet needed, and nothing you type into it is sent to us. If you tap “Search the web yourself”, your phone's browser opens a search site with your words. That search is between you and the search site: the app does not see, record or track what you do there. Please do not put your name, passport number or other personal details into a web search.
Who else handles data
- Cloudflare hosts our service, which serves the public rules, library and PSC data and these pages. It does not store anything about you.
- Google Play handles payments for Pro and the Student Pass, when they are offered. We do not see your card details.
- RevenueCat records which purchases you hold so the app can unlock Pro. It receives a random purchase ID made for your install and the purchase details from Google Play, not your name or documents. See revenuecat.com/privacy.
- If you choose to save an encrypted backup to Google Drive, iCloud, WhatsApp or e-mail, that service holds the encrypted file you chose to send. We never receive it.
We do not sell your information and we do not use it for advertising.
How long we keep things
- On your phone: until you delete it or uninstall the app.
Your choices and rights
- Delete your data on the phone at any time (or uninstall the app).
- Turn on the app lock in Profile to keep other people out of the app.
- We hold no personal data about you on our servers, so there is nothing for us to export or delete. Depending on where you live (for example under India's Digital Personal Data Protection Act or the EU/UK GDPR) you may have further rights; contact us to use them.
Security
Backups are encrypted on your phone (AES-256) with a passphrase only you know; we cannot open or recover them. Documents in the app are kept in the app's private storage and are protected by Android and your phone's screen lock; the optional app lock adds a PIN. On Android the app hides itself in the recent-apps list and blocks screenshots. No method is perfectly secure, so keep your phone locked and your backup up to date.
Permissions
Camera, to scan documents; notifications, for expiry reminders created on your phone; and the phone's file and share dialogs when you save or send a file. The app asks only when you use the feature.
Children
The app is for seafarers and for students planning a sea career, some of whom are under 18. We collect no account details and keep no personal data on our servers . We do not knowingly collect personal data from children under 13.
Changes
If we change what the app does with your information we will update this page and its date, and tell you in the app.
