đĨ Email Indexing
When you add an account, the app begins downloading and indexing your emails. This happens locally on your device â nothing is sent anywhere.
Initial Sync
The first sync downloads all your emails from the IMAP server and builds a searchable index. Depending on the size of your mailbox and your internet connection speed, this can take anywhere from a minute (small mailbox) to 20â30 minutes (very large mailbox).
You can watch progress in the Accounts screen where a progress indicator shows how many emails have been indexed. You can start searching immediately â results will appear for already-indexed emails while the sync continues in the background.
Background Sync
After the initial sync, the app checks for new emails at a configurable interval (default: every 15 minutes). New emails are added to the index automatically without any action needed from you.
đ Searching Your Email
The search screen is the main screen of the app. Tap the search bar and start typing â results appear instantly as you type.
What you can search
| Field | Detail |
|---|---|
| Subject line | Full-text search across all email subjects |
| Sender name | Search by the display name of the sender |
| Sender address | Search by email address |
| Email body | Full-text search of the complete email body content |
| Date | Results can be sorted by date (newest or oldest first) |
Search tips
Search is case-insensitive. You can search for partial words â "invoi" will match "invoice". For best results with common words, include more specific terms.
Reading an email
Tap any search result to open the full email. The email viewer shows the full body, sender details, date, and any attachments listed at the bottom.
đ Attachments
When viewing an email, attachments are listed at the bottom of the message. Tap an attachment name to download it to your device's Downloads folder.
Attachments are downloaded on demand â they are not pre-fetched during the initial sync. This keeps storage usage minimal.
đ Sync Settings
You can configure sync behaviour per account. Go to Accounts â tap account name â Settings.
| Setting | Options | Default |
|---|---|---|
| Sync interval | 5 min, 15 min, 30 min, 1 hour, Manual only | 15 min |
| Sync on WiFi only | On / Off | Off |
| Max emails to index | 1,000 / 5,000 / 10,000 / All | All |
đ Privacy
T2W Fast Email Search is designed with privacy as a core requirement, not an afterthought.
How your data is protected
| Data type | How it's stored |
|---|---|
| IMAP credentials (password) | Android Keystore encrypted secure storage â never stored in plain text |
| Email content | Local SQLite database on your device's internal storage |
| Attachments | Your device's Downloads folder (only when you request a download) |
What we never do
RANDH.TECH never receives, stores, or has access to your email content. Your emails travel directly from your email provider's IMAP server to your device and are stored only on your device. There is no RANDH.TECH server involved in any part of that journey.
â Frequently Asked Questions
Does the app work with two-factor authentication (2FA)?
Yes, but you need to use an App Password rather than your regular account password. Gmail, Yahoo, and Microsoft all support App Passwords. The app connects via IMAP which doesn't go through the OAuth flow, so App Passwords are the correct approach.
How much storage does the index use?
Typically 10â20KB per email for text-only messages, slightly more for HTML-heavy emails. A mailbox of 5,000 emails will typically use 50â100MB. Attachments only use storage when you explicitly download them.
Can I add more than one email account?
Yes. There's no fixed limit on the number of accounts. Each account is indexed separately but search results are shown across all accounts simultaneously.
Why isn't my Gmail IMAP connection working?
Almost certainly because you're using your regular Gmail password instead of an App Password. Google disabled basic IMAP authentication with regular passwords. You must enable 2-Step Verification first, then generate an App Password at myaccount.google.com/apppasswords. Use that 16-character code as your password in the app.
Will the app sync emails when my phone screen is off?
Yes, the app uses Android's foreground service to sync in the background. However, if you've set Android to optimise battery for this app, syncing may be paused. To ensure reliable background sync, set battery optimisation to "Unrestricted" for T2W Fast Email Search in Android Settings.
How do I delete an account and its data?
Go to Accounts â tap the account â scroll to the bottom â Remove Account. This immediately deletes all indexed emails and stored credentials for that account from your device. Uninstalling the app removes all data for all accounts.
Is this app free?
Yes, T2W Fast Email Search is free to install and use. It is currently in open testing on Google Play. No in-app purchases or subscriptions are planned.
đ§ Troubleshooting
Connection test fails
Check: Is the IMAP server address correct? Is the port 993? Is SSL/TLS selected? For Gmail, are you using an App Password? Is your internet connection active? Try disabling any VPN temporarily.
Sync stopped updating
Android battery optimisation may have paused the background service. Go to Settings â Apps â T2W Fast Email Search â Battery â Unrestricted. You can also manually trigger a sync by opening the app and pulling down to refresh on the Accounts screen.
Search not finding recent emails
If an email isn't appearing in search, it may not yet be indexed. Check the Accounts screen to see when the last sync completed. You can force a refresh by opening the Accounts screen and pulling down.
App is using too much storage
You can limit the number of emails indexed per account in account Settings â Max emails to index. Setting this to 5,000 or 10,000 most recent emails significantly reduces storage use for large mailboxes.
