Privacy Policy

1. Who we are

Felku is a sticker creation service, available through the WhatsApp bot and the native app (iOS and Android), operated by:

This policy describes how we collect, use, and protect your information when you use our service, whether through the WhatsApp Business Platform (Meta) or through the Felku app.

2. Data we collect

Through the WhatsApp bot:

• Phone number: used to identify your account and send the stickers you create.
• WhatsApp profile name: used to personalize communication.
• Images, videos, and GIFs you send: processed temporarily to create stickers. The original content is not stored after processing.
• Usage data: counters of stickers created, interactions with the assistant, and command history, for limit control and service improvement.
• Survey responses: when you choose to answer a survey within the bot, we record your responses and the profile data you provide (such as age range, gender, and region). Participation is always voluntary.

Through the Felku app:

• Device identifier: generated locally by the app, with no personal information, used to recognize your install.
• Push notification token: used to send alerts and updates within the app.
• Email: if you create an account in the app, we use your email for authentication and account recovery.
• Subscription status and history: whether and when the Felku Pro plan is active, processed by our subscription management partner (see Section 4). We do not have access to your card number or payment data itself — that stays with Apple or Google.
• App usage data: stickers created, screens visited, and features used, to improve the product.
• Astral Chart data, when you use that feature: birth date, time, and location you provide, used exclusively to calculate your astral chart.

3. How we use your data

• Create and send stickers as requested by you.
• Manage your account, usage limits, and subscription plan, on the bot and/or the app.
• Process subscription payments.
• Send notifications about pending stickers and service updates.
• Improve the service and fix technical issues.
• Conduct opinion surveys and generate aggregated reports and statistics, when you choose to participate (see Terms of Use, Section 8.1).
• Calculate and deliver your Astral Chart reading, when you use that feature.

4. Data sharing

We do not sell, rent, or share your personal data with third parties for marketing purposes. We share data only with:

• Meta / WhatsApp Business Platform: to send and receive messages. Meta processes the data according to its own privacy policy.
• Stripe: to process subscription payments made through the bot (PIX/credit card). Only the data necessary for the transaction is shared.
• Apple (App Store) and Google (Google Play): when you subscribe to Felku Pro through the app, payment is processed entirely by them — we do not receive your card data. We only receive confirmation that the subscription is active, through our subscription management partner (RevenueCat).
• RevenueCat: a platform that manages your app subscription status (active, canceled, renewed) between Felku and the Apple/Google stores. It processes only subscription data, not payment data.
• Supabase: for secure storage of account data (number, plan, counters). Data hosted on servers with encryption.
• Legal obligations: when required by Brazilian law or court order.
• Market research partners: when you participate in the Opinion Program (see Terms of Use, Section 8.1), we share the survey results with the partner research company in an aggregated or anonymized form. We never share your phone number, your name, or any data that individually identifies you.

Survey responses are handled in an aggregated or anonymized form before any sharing. The research partner receives statistics and trends from the pool of respondents — never the identity, phone number, or contact details of specific individuals. The delivery of rewards (credits) is carried out exclusively by us, within WhatsApp.

5. Storage and security

Your data is stored on secure servers with encryption in transit and at rest. Images and videos are processed temporarily and removed after the sticker is created. The stickers created are stored to allow resending when necessary.

6. Your rights

Under the Brazilian General Data Protection Law (LGPD — Brazil's data protection law), you may at any time:

• Request access to your personal data.
• Request the deletion of your data by sending "delete my data" in the WhatsApp conversation, or through the app's support.
• Stop using the service by no longer sending messages, or by uninstalling the app.

7. Data retention

We keep your account data while you use the service. After 12 months of inactivity, your data may be automatically removed.

8. Changes

We may update this policy periodically. Significant changes will be communicated via WhatsApp or through the app.
