Questions about getting started
How do I start using Gauss for budgeting?
Just add Gauss as a contact on WhatsApp and send a "hi". In under 5 minutes you are already logging expenses. No app to download, no account to create, no forms to fill out. Gauss walks you through everything right in the chat as soon as you start the conversation.
Do I need to download a new app to use Gauss?
No. Gauss works 100% inside WhatsApp, which you probably already use every day. No additional download required. Just add the contact and start sending messages.
How long does it take to get set up?
Less than 5 minutes. You send an initial message, Gauss introduces itself and explains how it works, and you can log your first expense right after. No forms to fill out, no complicated settings to configure.
Do I need to be tech-savvy to use Gauss?
If you know how to use WhatsApp, you know how to use Gauss. The interaction is through plain text messages in natural language — the same way you text anyone. No menus, no special commands, no required tutorials.
Questions about expense logging
How do I log an expense in Gauss?
Send a natural language message like "lunch $12" or "paid $87 at the grocery store". Gauss understands the context, identifies the category automatically, and confirms the entry in seconds. No specific format required, no codes, no date needed — Gauss fills in what is missing.
Can I log several expenses at once?
Yes. You can send a list in a single message: "groceries $87, Uber $14, pharmacy $22". Gauss processes each item separately, categorizes them all, and confirms everything at once. Useful for logging the day's spending before bed.
What if I forget to log an expense right away?
No problem. You can log it later with the correct date, like "yesterday I spent $45 on dinner". Gauss records it on the date you mention. There is no penalty for logging late — the goal is to have the data, not perfection in timing.
Can I log income as well, not just expenses?
Yes. You can tell Gauss about incoming money — salary, freelance payment, a sale — and it includes that in your financial history. This gives you a view of your real balance, not just your spending.
Questions about categories and organization
How many categories do I need to track my spending?
7 categories are enough to cover 90% to 95% of most people's spending. According to the Consumer Financial Protection Bureau (CFPB), the main household spending categories are housing, food, transportation, healthcare, entertainment, education, and personal care. More than 10 categories starts creating friction at the moment of logging. Learn more in the article on 7 categories to track your expenses.
Can I create custom categories in Gauss?
Yes. If the default categories do not reflect your reality, you can create your own. Just tell Gauss how you want to organize your spending. It learns and applies your categories to future entries.
What happens when Gauss categorizes something incorrectly?
You correct it immediately with a simple message, like "that expense is transport, not entertainment". Gauss fixes the entry and learns from your correction for similar future cases. Over time, errors become rare.
Can I change my categories after months of use?
Yes, but it is worth thinking it through first. If you already have history under a category, changing it may affect comparisons with earlier periods. The ideal approach is to adjust at the beginning and then keep categories stable so your data stays comparable over time.
Questions about reviews and reports
How do I see a summary of my spending in Gauss?
Just ask directly in the chat. Send messages like "how much did I spend this week", "food summary for the month", or "compare this week to last week". Gauss replies immediately with the numbers organized by category.
Does Gauss send automatic reports?
Gauss can send periodic summaries if you set that up. But you can also ask at any time — you do not have to wait for a scheduled report. On-demand queries are one of the advantages Gauss has over traditional spreadsheets and budgeting apps.
How many days of data do I need before I can see useful patterns?
With 7 days you can already see where you are spending the most. With 30 days you have a solid baseline for setting realistic limits. With 3 months you start to see seasonal patterns — months with more entertainment spending, periods of higher health costs, and so on.
Questions about privacy and security
Does Gauss share my financial data with anyone?
No. Gauss never shares your financial data with third parties. Your information is used exclusively to generate your personal reports. Gauss follows best practices aligned with international privacy standards, including GDPR principles, ensuring your data is only used for the purposes you authorized.
Is my financial data stored securely?
Yes. Gauss data is stored with encryption on secure servers. You can request deletion of your data at any time — that is a right you always have. See our privacy policy for full details.
Does Gauss have access to my other WhatsApp conversations?
No. Gauss only sees the messages you send directly to its contact in your chat with Gauss. Your other conversations, group chats, and files on WhatsApp are completely invisible to Gauss.
What happens to my data if I cancel my subscription?
You can request the export or deletion of your data at any time, including after cancellation. Gauss respects your rights as a data subject under applicable privacy laws.
Questions about family and shared use
Can my partner and I use Gauss together without mixing our data?
Yes. Each person has their own independent Gauss conversation and maintains individual privacy. Couples can choose to share specific reports when they want — for example, a monthly joint summary — but that is never automatic. Learn more in financial control for couples.
Can I use Gauss to track the whole household's spending?
Yes. You can log spending for the entire household in Gauss, creating specific categories for each family member or for shared expenses. It is a practical way to get a consolidated view of the household finances.
If my partner also uses Gauss, will their data show up in my profile?
Not automatically. Each account is independent. If you both want a shared view, that can be configured — but always with both people's consent. Gauss never merges data from different accounts without authorization.
Questions about plans and pricing
How much does Gauss cost?
Gauss plans start at $5 per month. The mid-tier plan is $9 per month and the full plan is $15 per month. All plans include the core logging and reporting features. The differences are in data history length and advanced analytics capabilities.
Do I need a credit card to try Gauss?
No. The 14-day free trial does not require a credit card. You get full access to all features for 14 complete days and only decide about a paid plan at the end of that period. If you choose not to continue, there is no automatic charge.
Is 14 days enough to decide if Gauss is worth it?
Yes. With regular use over 14 days — logging expenses daily — you will have enough data to see spending patterns, test the reports, and feel whether Gauss fits your routine. Most people decide within the first week.
Can I cancel anytime?
Yes. There is no lock-in contract and no cancellation fee. If you decide Gauss is not for you, you cancel and that is it. No bureaucracy, no customer service call required.
