Privacy Policy

IP Address Storage:

  • We temporarily store your IP address for 7 days
  • This information is used solely to limit the number of birthday cards created per user
  • We do not use this information for tracking, profiling, or marketing
  • IP addresses are automatically deleted after 7 days
  • We do not sell your IP address or share it with advertisers
  • We also use your IP address to detect your timezone for accurate event scheduling
  • To find your IP address and timezone, your browser contacts ipapi.co and ipify.org directly, so those services receive your IP address as part of that request

Image Storage:

  • Images you upload when creating birthday cards are stored on our servers
  • We do not use these images for any purpose other than displaying your card
  • Images are retained for as long as the card exists and are deleted when the card expires

Card Data Retention:

  • Birthday card content (messages, names, etc.) is stored on our servers
  • All cards automatically expire and are deleted after 7 days from creation, or one year after payment for a card with a paid custom link
  • We do not use this content for any purpose other than displaying the card
  • So you can find a link again, the cards you make are listed under “Your cards” on the card maker. That list (the link, the recipient's name and the card title) is kept only in your browser's storage, is never sent to us, and drops each card once it expires

“Write it for me” (AI message ideas):

  • If you ask for message ideas, we send the occasion, the tone you pick, whether the card has an age, and anything you type in “Anything to mention?” to a model run by Cloudflare Workers AI. The recipient's name, your name and the age are not sent: the name is added on your device
  • The ideas are kept for up to 7 days, in Cloudflare's cache (with the request above) and in your browser's storage, so the same request gets an answer without asking the model again. Don't type anything private in “Anything to mention?”

Payments:

  • If you pay for a custom card link or leave a tip, the payment is handled by Razorpay. Your card number, UPI details and bank details go to Razorpay, not to us
  • Razorpay may ask for your email address and phone number to process the payment and send a receipt; it handles them under its privacy policy
  • We keep the Razorpay payment and order IDs with the card so a payment can be matched to its card if there is a problem. They are deleted with the card
  • Razorpay keeps its own payment records, as the law requires of payment companies
  • If you pay in US dollars, you pay with PayPal on PayPal.me, and whatever you enter there is handled under PayPal's privacy statement

Cookies & Analytics:

  • We use Google Analytics, loaded through Google Tag Manager, to understand how many people visit the site and which pages they use
  • We use Google Consent Mode: if you are in the EEA, the UK, or Switzerland, analytics and advertising cookies stay disabled until you consent, and you can change your choice at any time through the consent dialog
  • We also use Cloudflare Web Analytics, which is cookieless and does not track individuals across sites
  • We do not sell your data or use it to build advertising profiles ourselves
  • See how Google uses data from sites that use its services

Advertising:

  • We may display advertisements served by Google AdSense
  • Google and its partners may use cookies to serve ads based on your prior visits to this or other websites, subject to the consent choice described above
  • You can opt out of personalised advertising in your Google Ad Settings
  • For more information about Google's advertising practices, please visit Google Advertising Policies

Microphone Access:

  • Birthday cards ask for microphone permission so the candles can be blown out
  • Audio is analysed in your browser only — it is never recorded, stored, or sent to our servers
  • Declining the permission does not prevent you from viewing the card

Data Security:

  • We implement reasonable security measures to protect your data
  • Data is stored in secure cloud environments with industry-standard protections
  • We regularly review our data handling practices to maintain appropriate security
