Privacy Policy

• Account details: your name and email address. If you sign in with Google, we receive your name and email from Google.
• Profile details: your mobile (WhatsApp) number, date of birth, preferred currency and timezone, and whether your number has been verified.
• Financial entries you create: transactions (type, amount, description, category, date, payment method), budgets, custom categories, and your savings and investment records.
• WhatsApp and AI chat: the messages you send to the HeyFyn assistant and its replies. We keep recent conversation history so the assistant has context, and delete it automatically after 30 days.
• Subscription records: your plan, trial and renewal dates, and the Razorpay subscription and payment identifiers. We do not receive or store your card or bank details; Razorpay handles those.
• Technical data: your IP address and request details, used to keep the service secure and to limit abuse. Your login tokens are kept in your browser's local storage.

• To create your account, sign you in with one-time codes, and keep your account secure.
• To store, categorise and display your financial entries, charts and budgets.
• To understand your chat messages and turn them into transactions with the AI assistant.
• To send WhatsApp reminders and daily summaries if you have verified your number and have an active trial or subscription.
• To process subscription payments and prevent fraud and misuse.
• To respond to your support requests and to meet legal obligations.

We do not sell your personal information and we do not use it for third-party advertising.

We use trusted service providers who process data on our behalf, only as needed to run HeyFyn:

• Neon hosts our cloud database, which holds your account and financial data.
• OpenAI receives the text of your AI chat messages, your custom category names and the current time in your timezone, so it can extract transactions. We do not send your name, email address or phone number to OpenAI.
• Meta (WhatsApp Business Platform) delivers WhatsApp messages and receives your number and the message content.
• 2Factor.in sends SMS verification codes to your mobile number.
• Google provides Google Sign-In if you choose it.
• Razorpay processes subscription payments.
• An email delivery provider sends one-time codes, and product news if you turned it on, to your email address.

These providers may process data on servers outside India. We may also disclose information when required by law or to protect our rights and users.

HeyFyn does not set advertising or tracking cookies. We use your browser's local storage to keep you signed in and session storage for small interface preferences. Google Sign-In and Razorpay Checkout may set their own cookies when you use them, under their own policies.

We keep your information while your account is active. You can delete your account and data at any time (see section 7). Payment and billing records are kept for as long as the law requires, no longer linked to you. To stop a phone number from claiming the free trial twice, we keep a one-way code made from it (not the number itself) after the account is deleted.

We use encrypted connections (HTTPS), store one-time codes only in hashed form, limit repeated login attempts, and restrict access to our systems. No system is completely secure, so we cannot guarantee absolute security. Please keep your email account and phone secure.

You can download a copy of your data, and delete your account, yourself: open your Profile and use Your data. You may also ask us to access, correct or delete your personal information, or to withdraw your consent to processing. To make a request, email support@katlyzt.com from the email address on your account. We verify your identity first and aim to complete requests within 30 days. Deleting your data ends your ability to use the service. You can stop WhatsApp messages at any time by emailing us, or by removing your number from your profile. Product news by email is off unless you turn it on in your Profile, and every such email has a link to unsubscribe.

HeyFyn is intended for people aged 18 and over. We do not knowingly collect information from children. If you believe a child has given us information, contact us and we will delete it.

We may update this policy from time to time. We will change the "Last updated" date above, and for significant changes we will take reasonable steps to notify you.
