Terms of use
1. The service and the parties
LagerOS is an online app for the stock, sales and finances of small businesses: items with barcodes, receiving goods and stock levels, checkout by scanning, ledgers and payments. Parts of the app (modules) are turned on per business. The service is provided by Milan Milić ("LagerOS", "we"). The customer is the company or sole trader that opens an account (the "business"). The service is intended for business use, not for consumers.
These terms, the Privacy policy and the Data processing agreement form the contract between LagerOS and the business.
2. Acceptance
The business accepts these terms and the Data processing agreement when it starts the free month or makes its first payment. Every user the business adds acts on behalf of the business and under these terms.
3. Accounts and users
- The business owner adds users and decides what each of them can see and change.
- Accounts are personal. Passwords are not shared and are kept secret.
- The business is responsible for what its users do in the app.
- If you suspect someone is misusing an account, change the password at once and contact us.
4. Modules, free month and payment
- The business chooses a package and a plan (Start or Pro) from the price list on this website. Within the package it chooses the modules it uses (for example Warehouse and Checkout). For arrangements outside the price list, the offer the business receives before it starts paying applies.
- The first month is free, with no obligation to pay.
- Payment is monthly or yearly, in euros or in dinars at the National Bank of Serbia middle rate on the day of payment. The payment method is agreed when signing up.
- The provider is not registered for VAT, so no VAT is charged on the prices.
- The subscription is valid until the date the owner sees on the Company page. Expiry reminders arrive 7 days and 3 days before, and on the day of expiry.
- If the business changes its package or plan, the new price applies from the next billing period.
- We announce price changes at least 30 days in advance. They do not affect a period already paid for.
5. When the subscription expires
- For the first 7 days after expiry the app is read-only; changes are not possible.
- After that, access is closed, but the owner can still export the business's data.
- Once a payment is recorded, work continues immediately with all data.
- If no payment is made within 90 days of closing, we may delete the business's data, after notifying the owner by email at least 14 days in advance.
6. What LagerOS is and is not
LagerOS is the business's internal record-keeping: goods, stock, sales, debts and payments. It does not issue fiscal receipts; the receipt the app prints is not a fiscal receipt. It sends invoices to the e-invoicing system (SEF) only if the business turns on that module and enters its own API key, and only when a user sends the invoice. It does not connect to banks and, apart from that, does not send data to public authorities. It is not accounting software. The business fulfils its own legal obligations (fiscalisation, sales records, tax returns, bookkeeping and similar).
Stock levels, profit and debts in the app are calculated from what users enter. They are as accurate as the entries, so the business checks its stock from time to time with a stocktake.
7. AI assistant and import from image
The AI assistant answers questions about using the app, from the user guide, and helps describe a problem report clearly. An answer can be wrong or incomplete, so check important steps in the guide or contact us. “Import from image” (Pro plan) suggests items, prices and barcodes from an image or PDF; a suggestion can contain mistakes, so the user checks it before saving. AI is meant for reasonable use; if usage is unusually high, we will get in touch to agree on it.
8. The business's data
- Data the business enters belongs to the business. The owner can export it to Excel, and on request we send a full copy of the business's data.
- The business is responsible for having a legal basis for the data it enters (for example, doing business with a customer or supplier) and for informing the people the data concerns.
- We process that data only to provide the service, under the Data processing agreement, and do not use it for any other purpose.
- We may use aggregate numbers without personal data (for example, how many businesses use a module) to develop the service.
9. Acceptable use
It is not allowed to:
- enter unlawful content or data for which the business has no legal basis;
- try to access other businesses' data or parts of the system not meant for the user;
- overload the system, scrape data automatically, or bypass security;
- resell the service without our written agreement.
If these rules are broken, we may suspend access temporarily and will inform the owner.
10. Availability and support
- We aim to keep the app running at all times but do not guarantee uninterrupted operation. Checkout needs an internet connection.
- We do maintenance outside working hours where possible and announce it if it takes longer.
- We make backups every day.
- Support: problem reports from the app, [email protected] and +381 64 186 0217, on working days.
- We keep developing the app. Features may change, but we do not remove essential parts of paid modules without notice.
11. Liability
- We provide the service as it is, with the care of a prudent business.
- We are not liable for lost profit or indirect damage, or for damage caused by incorrectly entered or unchecked data (for example, a wrong stock level or price).
- LagerOS's total liability is limited to the amount the business paid in the last 12 months.
- These limits do not apply to damage caused intentionally or by gross negligence.
12. Cancellation and termination
- The business may cancel at any time by writing to [email protected]. The service runs until the end of the paid period; amounts paid are not refunded.
- We may terminate with 30 days' notice, or immediately if the business seriously breaches these terms.
- After the service ends, the owner has 30 days to export the data. We then delete it, and it disappears from backups within the following 30 days.
13. Changes to the terms
We publish changes on this page and announce them to the owner by email or in the app at least 30 days in advance. If the business disagrees, it can cancel before the changes take effect. Continuing to use the service after that date means acceptance.
14. Governing law and disputes
These terms are governed by the law of the Republic of Serbia. We resolve disputes by agreement; failing that, the competent court in Belgrade has jurisdiction.
