Last updated: February 2026
Introduction
Lightswap ("we," "our," or "us") is a financial management application that helps users manage their bank accounts, track spending, and access brokerage services — all from a single app. This Privacy Policy explains how we collect, use, store, and protect your information when you use our website, mobile application, and related services (collectively, the "Service").
By using the Service, you consent to the collection and use of your information as described in this policy. If you do not agree with this policy, please do not use the Service.

Data belonging to US customers will never be transferred to or stored on EU servers, and data belonging to EU/UK customers will never be transferred to or stored on US servers. These datasets are kept strictly separate.

We never sell your personal data. We share information only with the following categories of service providers, solely to operate the Service:

Data Security
We maintain a comprehensive information security programme designed to protect your data. Our security measures include:
Zero-Knowledge Architecture
- Your API keys, private keys, and bank login credentials are never stored on our servers
- Sensitive credentials are encrypted and stored locally on your device using the iOS Keychain
- Brokerage and exchange operations are executed directly from your device — our server never has access to your third-party accounts
Encryption & Access Controls
- All data in transit is encrypted using TLS/HTTPS with HSTS enforcement
- Sensitive data at rest (email addresses, passwords) is cryptographically hashed
- Bank account access tokens from financial data providers are used ephemerally and are not retained on our servers
- Access to data is restricted to authorised personnel with a demonstrated business need
Monitoring & Incident Response
- We monitor our systems for unauthorised access and suspicious activity
- Payment consent records are maintained in append-only audit logs that cannot be altered or deleted
- In the event of a data breach affecting your personal information, we will notify you and the relevant supervisory authorities in accordance with applicable law
Data Retention
We retain your data only for as long as necessary for the purposes described in this policy:
- Financial data (balances, transactions): Processed in real time to generate insights and not stored long-term on our servers. Cached temporarily for the duration of your session only.
- Payment records & consent audit logs: Retained for a minimum of 5 years to comply with financial services regulations.
- Feedback data: Retained for 2 years from submission, then automatically deleted.
- Device and usage data: Retained for as long as your account is active, then deleted within 90 days of account closure.
- Waitlist data: Retained until the waitlist programme ends or you request removal.
When data is no longer required, we delete or anonymise it. Where deletion is not immediately possible (e.g., data in backup systems), we isolate and protect the data until deletion is feasible.
