Switching phones
Back up to Google Drive on the old phone, restore on the new one. Every thread comes across.
THREE THINGS, ONE APP
Everything your texts need, without handing them to anyone.
Back up & restore
Save every SMS on your phone in one tap, or just a date range. Restore them on a new phone without losing a thread. Duplicates are skipped.
- Save to this phone, Google Drive, a Google Sheet or email
- Restore from a backup file, with a summary first
- Keeps which SIM each text came in on
Web view
Scan a code once, and every new SMS shows up in your browser seconds after it reaches your phone. Pair more than one phone: each is kept separate and labelled.
- Encrypted on your phone, saved only in that browser
- Works in Chrome, Edge, Firefox and Safari on a Mac
- Unpair from either side; the texts are removed
Automations
Build your own rules: choose when they run, what they look for, and where texts go.
WHEN
A new SMS arrives, on a schedule, or when the phone restarts
ONLY IF
The sender or the text contains words you pick
DO
Send to Slack, a webhook, Google Drive or Gmail

FAQ
Questions, answered plainly
PRIVACY
Do you collect or store my texts?
No. ZapBridge runs locally on your phone. Roshi Software Solutions never receives your texts, contacts, or anything from your Google account.
Texts go only where you send them: a backup file you choose, a browser you paired, or the destination an automation names.
Does ZapBridge ever send SMS from my phone?
Never. ZapBridge doesn't even ask for permission to send SMS, so it can't send texts, can't cost you SMS charges, and can't text anyone in your name. It only reads SMS for the features you turn on.
Can ZapBridge read my Gmail or my Google Drive?
No. For Gmail it asks only to send email, so it can't read your inbox. For Google Drive it can see only the files ZapBridge itself created. You connect them only if a backup or an automation needs them, and you can disconnect any time in Settings.
Is anything sold, shared for ads or tracked?
No. There are no ads, no analytics and no tracking in the app or on this website, and nothing is sold or shared with anyone.
How are texts sent to my laptop kept private?
Each text is encrypted on your phone and only the browser you paired can decrypt it. It travels through your browser's own notification service (for example Google's for Chrome, Apple's for Safari), which can't read it. The browser saves texts only on that computer.
What does ZapBridge keep on my phone, and for how long?
- Texts waiting to be sent by an automation, until they're sent.
- A record of what was sent: 7 days. Messages that couldn't be sent: 30 days, so you can retry them.
- The activity log: 7 days (at most 1,000 entries).
- Battery-use figures: 8 days.
All of it stays on the phone and is deleted when you turn everything off or uninstall the app.
PERMISSIONS
Why does ZapBridge need SMS permission?
To read the texts it backs up, restores, shows on your laptop or passes to your automations. It asks only when you start one of those features for the first time, and explains why first. Until then it has no access to your SMS.
When is each permission asked for?
- SMS: when you first back up, pair a browser or create an SMS automation.
- Notifications: when you save your first automation.
- Contacts: only if you turn on "Show contact names".
- Camera: never. Pairing uses Google's code scanner, which doesn't give ZapBridge camera access.
Say no to any of them and the rest of the app keeps working.
What are notifications used for?
On your phone: to tell you a backup or restore finished, an automation couldn't send something, or Gmail or Drive needs you to sign in again. No promotions, ever.
On your laptop: notifications are how new texts reach the browser, even when the tab is closed. By default they say only who the text is from; you can choose to show the text too.
Why does ZapBridge ask to become the default SMS app during a restore?
Android lets only the default SMS app write texts back to the phone. ZapBridge asks for it only while a restore runs, then helps you switch back to your usual messaging app.
How do I take a permission back?
Any time, in Android Settings › Apps › ZapBridge › Permissions. Features that need it pause and tell you why.
USING ZAPBRIDGE
Does it work with MMS or RCS chats?
Not yet. ZapBridge handles SMS only.
Will it drain my battery?
No. It never stays running in the background: it wakes only for a new SMS, a schedule or a restart. The Battery use screen shows exactly how often it woke up and for how long.
Can I pair more than one phone with my laptop?
Yes. Each phone's texts are kept separate and labelled, and you can rename or remove phones in Devices.
Is there an iPhone version?
No. iPhones don't let apps read SMS, so ZapBridge is Android only.
YOUR PRIVACY RIGHTS, WHEREVER YOU LIVE
Which privacy laws does ZapBridge follow?
ZapBridge is built to respect your rights under the privacy laws that apply where you live, including the EU and UK GDPR, the California Consumer Privacy Act (CCPA/CPRA), India's Digital Personal Data Protection Act (DPDP), Brazil's LGPD and similar laws. The simplest protection comes first: the app runs locally on your phone, so we don't hold your texts at all.
Who is responsible for my data?
Roshi Software Solutions Pvt Ltd makes ZapBridge. Your texts and contacts are processed on your own device, on your instructions, and we don't receive a copy. When you send them to a service like Gmail, Google Drive or Slack, that service is responsible for them under its own privacy policy.
On what basis is my data used?
Your consent, given feature by feature when you turn something on, and only to do what you asked: back up, restore, show texts on your laptop, or run your automations. Nothing is used for advertising, profiling or training.
How do I withdraw consent?
Any time, as easily as you gave it: turn the feature off, disconnect Gmail or Drive in Settings, revoke the permission in Android, or use Settings › Turn off everything and sign out. Withdrawing doesn't affect what was already done.
How do I access, export, correct or delete my data?
- Access: everything ZapBridge keeps is visible in the app (the activity log, each automation's history).
- Export: a backup gives you all your SMS in a file you own.
- Delete: Settings › Turn off everything and sign out deletes everything ZapBridge kept and tells paired browsers to delete their texts. Uninstalling also deletes it.
Backup files you saved to Drive, email or elsewhere stay there until you delete them.
Do you sell or share my personal information?
No. We don't sell or share personal information for advertising, as the CCPA defines those terms, and we never have.
Is my data transferred to other countries?
ZapBridge doesn't move your data anywhere you didn't choose. If you send texts to a service such as Gmail, Google Drive or Slack, that service may store them in other countries under its own safeguards.
Can children use ZapBridge?
ZapBridge is meant for adults (18+) and isn't directed at children. We don't knowingly process children's data.
Who do I contact with a privacy request or complaint?
Write to our privacy contact, Nishant Bhatia, at contact@roshi.in. We reply within 10 days. You can also complain to the data protection authority where you live, for example your EU or UK supervisory authority or the Data Protection Board of India.
Full details are in our privacy policy.
