Privacy & Data

Subscrypts Pulse is built on a custodian-free, privacy-first design. It monitors your subscriptions by reading public blockchain data — without accessing your wallet, collecting personal information, or tracking your activity.

Custodian-Free Design

Pulse is read-only:

  • It never asks for private keys, seed phrases, or wallet passwords
  • It cannot initiate transactions, transfer funds, or interact with your wallet
  • It only reads public data from the Arbitrum blockchain (subscription status, balances, plan metadata)

You provide your public wallet address — Pulse reads on-chain data associated with that address. That's the full extent of the interaction.

What Data Pulse Stores

Pulse stores the minimum data needed to deliver its monitoring and notification services:

Data Purpose Retention
Device push token Deliver push notifications to your device Until device is unregistered
Public wallet addresses Monitor subscriptions and balances on-chain Until wallet is removed or device is unregistered
Wallet labels Display friendly names in the UI Until wallet is removed or device is unregistered
Notification preferences Respect your per-type toggles, quiet hours, and thresholds Until device is unregistered
Notification history Display past notifications in-app Auto-deleted after 90 days
Device metadata Platform (iOS/Android/web), app version Until device is unregistered

What Data Pulse Does Not Collect

  • Personal information — No names, emails, phone numbers, or addresses
  • Private keys or seed phrases — Never requested, never transmitted, never stored
  • Transaction signing — Pulse cannot prompt you to sign transactions
  • Analytics or tracking — No behavioral analytics, no advertising trackers
  • Chat messages or social data — Pulse has no access to your Telegram, Discord, or other platform data

GDPR Compliance

Pulse supports complete data erasure in compliance with GDPR (General Data Protection Regulation) principles:

Unregistering Your Device

In Settings, you can unregister your device. This triggers a cascading delete that removes:

  • Your device registration
  • All monitored wallet addresses and labels
  • All notification preferences
  • All notification history

After unregistering, Pulse retains zero data about your device or wallets. This is an irreversible action.

How to Unregister

  1. Open Settings in Pulse
  2. Scroll to the bottom
  3. Tap Unregister Device
  4. Confirm the action

Irreversible

Unregistering deletes all your data permanently. If you want to use Pulse again, you'll need to re-add your wallets and reconfigure your preferences.

Data in Transit

All communication between Pulse and its backend is encrypted:

  • HTTPS/TLS — All API requests use encrypted connections
  • Push notifications — Delivered via encrypted channels (FCM/APNs for mobile, VAPID for web)

Comparison with Traditional Monitoring

Subscrypts Pulse Traditional Subscription Managers
Private keys required Never Often (for connected accounts)
Personal data collected None Email, name, payment details
Data erasure Complete on unregister Varies; often incomplete
Analytics tracking None Common (behavioral, advertising)
Permissions needed Notifications only Broad device access typical
