⚡ Four fixes that solve most problems
1 · "The app won't open after an update"
Restart the device first. Do not uninstall — that removes your local database. If a restart doesn't help, write to us before uninstalling anything.
2 · "My second device isn't syncing"
Check, in order: is the hub device's app actually open (sync runs in the foreground only); are both devices on the same Wi-Fi network; and is there anything waiting in More → Records needing review? A flagged conflict freezes that record until a person chooses.
3 · "The tax on my bill looks wrong"
The CGST+SGST versus IGST split comes from your shop's state compared with the bill's place of supply. Check More → Business profile → State, then the customer's saved state — a customer saved with the wrong state will keep producing wrong bills until their record is fixed.
4 · "My stock has gone negative"
Something was sold that the app didn't know you had — usually stock that arrived without a purchase being recorded. Record the purchase, or a stock adjustment with a reason, and the balance corrects itself.
✉️ Write to us
One address, and a real person reads it. We aim to reply within 2 working days.
support@myappscart.comWhat to include so we can help on the first reply
- Platform and version — Android, iPhone, Mac or Windows, and the app version from More → Help.
- What you were doing — the screen you were on and the step that failed.
- What you expected, and what happened instead.
- A screenshot if there is anything to see.
- Whether it happens every time or only sometimes.
💡 Requesting a feature
Feature requests are welcome and genuinely read. The most useful ones describe the situation at your counter rather than the solution — "I sell loose sweets and customers ask for 250 g" tells us far more than "add a decimals option", because it lets us solve the real problem.
You can also send feedback from inside the app: More → Feedback.
🐞 Reporting something that looks wrong with a number
We take arithmetic bugs more seriously than anything else, because a wrong figure travels as far as a filed return. If a total, a tax split, a stock balance or a khata balance looks wrong:
- Note the document number and the exact figures shown.
- Take a screenshot of the bill or the statement.
- Email us with "Figure check" in the subject line — these go to the front of the queue.
🔒 Privacy, data & deletion
- Privacy Policy — what stays on your device and what the optional cloud features send.
- Delete your account & data — how to remove local data, cloud data, or both.
- Terms of Service — the agreement, in plain words.
🧾 About billing and plans
Subscription questions — a payment that succeeded but hasn't unlocked, a refund, or changing plan — go to the same address. Include the date and amount of the charge and the email or account you paid with.
If a payment succeeded but the plan hasn't appeared, first reopen More → Subscription and give it a moment: the app checks with the server rather than trusting itself, so it can take a few seconds.
🏢 About us
HisabNova is built by MyAppsCart, an independent app studio. We build small, focused apps that work offline, need no account, and don't track you. HisabNova is the same idea applied to a shop's books.
