Terms of
Use

GST Send is provided by Aier Labs (“we”, “us”). By using the app you agree to these terms.

GST Send helps you create GST invoices, calculate tax, generate PDF invoices, and email them to your customers. It stores your records on your device and, once you sign in, synchronises them to our servers.

GST Send does not provide tax, accounting, or legal advice. You are responsible for the accuracy of every invoice you issue, for the tax treatment you select, and for meeting your filing and record-retention obligations. Verify your invoices before sending them.

You can use GST Send as a guest, with your records stored only on your device. Finalising an invoice and emailing it require an account, because both are performed on our servers.

You are responsible for keeping access to your email address and sign-in method secure. Tell us promptly at gstsend@aierlabs.com if you believe your account has been used without your permission.

The free plan includes:

• One business
• Unlimited customers and products stored locally
• Five finalised invoices per calendar month
• Five canonical PDFs per calendar month
• Three invoice emails per calendar month
• The minimal and modern invoice designs for finalised invoices
• Guest mode and offline draft creation

Invoices carry no watermark on any plan.

GST Send Pro is an auto-renewing subscription offering up to five businesses, unlimited finalised invoices subject to abuse protection, up to 500 invoice emails per rolling 30 days, every invoice design, cloud synchronisation, canonical PDF history, exports, and subscription restoration.

Pro is sold as a monthly or yearly subscription through the Apple App Store or Google Play.

• Price in India: ₹149 per month or ₹1,499 per year. Prices in other markets are converted by the store and shown to you before you confirm.
• Payment is charged to your store account when you confirm the purchase.
• The subscription renews automatically for the same period and price unless you cancel at least 24 hours before the end of the current period.
• Manage or cancel your subscription in your Apple or Google account settings. We cannot cancel it for you.
• New subscribers get a three-day free trial before the first charge. You are charged at the end of the trial unless you cancel before it ends. The trial is offered once per store account, and the store decides eligibility.

Purchases are made through Apple or Google, and refunds are governed by their policies. Request a refund through the store you purchased from. Where a store notifies us that a purchase has been refunded or revoked, we remove the corresponding access.

We do not offer a separate refund process of our own, because we never take your payment directly — Apple and Google do.

Downgrading never deletes your data. Existing invoices remain readable and exportable. Actions reserved for Pro stop working once your entitlement expires. If you are over the free-plan business limit, your existing businesses remain accessible but you cannot create new ones until you are within the limit.

Access may continue briefly offline after expiry, for at most 72 hours, and never beyond the expiry or grace deadline reported by the store.

You agree not to:

• Use GST Send to issue invoices that are fraudulent or that you know to be inaccurate
• Send invoice emails to recipients who have not agreed to receive them, or use the email feature to send unsolicited bulk messages
• Attempt to access another user's data, or to bypass plan limits, rate limits, or entitlement checks
• Reverse engineer, disrupt, or place unreasonable load on the service

We may suspend or terminate an account that breaches this section. Where we do, we will tell you why and, unless prevented by law, give you an opportunity to export your data.

Your business, customer, product, and invoice data is yours. You grant us only the permission needed to store, process, render, synchronise, and transmit it in order to run the service for you.

We aim to keep GST Send available and working, but we do not guarantee uninterrupted service, and we do not offer a service level agreement or an uptime guarantee on any plan.

The app is designed to keep functioning offline. Because your records are held on your device first, an outage on our side stops finalising, emailing, and syncing, but it does not stop you creating or reading your invoices.

You can ask us to delete your account at gstsend@aierlabs.com. We delete data not subject to legal retention within 30 days. Invoice and tax records are kept only for the applicable statutory retention period, restricted to legal and operational use, and deleted when that period ends. Deleting your account does not cancel a subscription — cancel that in your store account.

Nothing in these terms limits liability that cannot be limited by law, including for death or personal injury caused by negligence, or for fraud.

Subject to that, we are not liable for indirect or consequential loss, or for loss of profit, revenue, or data arising from your use of GST Send. Our total liability to you for all claims arising in any 12-month period is limited to the greater of the amount you paid us for GST Send in the 12 months before the claim arose, or ₹5,000.

You remain solely responsible for the correctness of the invoices and tax figures you issue.

We may update these terms as the service changes. We will revise the effective date and, for material changes, tell you in the app or by email.

These terms are governed by the laws of India. Any dispute arising from them is subject to the exclusive jurisdiction of the courts at Bengaluru, India.

Nothing here removes any right you have under consumer protection law in the country you live in.
