Privacy policy

Last updated October 19, 2026

The short version

1. Who we are and what this policy covers

CostBook is run by Cloyd C. Abad, a sole proprietor doing business as Stewardship Website Application Services, Dumaguete City, Philippines ("CostBook", "we", "us"). This policy explains how we handle personal information when you visit this website, use the CostBook app, receive a quote sent through CostBook, or contact us.

We have two roles, and the policy treats them separately:

2. What we collect

When you sign up and use CostBook

Automatically, while you use the app

When you subscribe

Creem handles checkout and payment as our merchant of record. It collects your payment and billing details under its own privacy policy. We receive and keep your Creem customer and subscription IDs, your plan, your subscription status, your trial and billing dates, and whether the subscription is set to cancel. We never see or store your full card or bank details.

When you contact us

If you email us, we keep your message and our reply so we can help you, and handle any follow-up.

When you visit this website

This marketing website sets no cookies and uses no third-party analytics, advertising or tracking scripts. Fonts are served from our own server. We count visits ourselves, anonymously: see Counting visits to this website. As with any website, the server logs each request (IP address, page, time and browser) to keep the site running and secure.

We don't ask for sensitive personal information (such as health, religion, government ID numbers or biometrics), and CostBook isn't designed to hold it. Please don't put it in notes or files.

3. How we use it, and why we are allowed to

We don't sell personal information, use it for advertising, build profiles, or use it to train AI models. CostBook makes no automated decisions about people that have legal or similarly significant effects.

If you choose not to give us information the service needs, such as an email address, we may not be able to give you an account.

4. If you received a quote through CostBook

Businesses use CostBook to prepare and send quotes. If a business sent you a quote, that business controls your information and its own privacy notice applies. We process your information on its behalf. Here is what that involves:

To access, correct or delete your information, please contact the business that sent you the quote. If you contact us instead, we'll pass your request on to them and help them respond. You can reach us at cloyd.abad@costbook.app.

5. Who we share it with

We share personal information only with the service providers below, and only as each one needs to provide its service to us. Each of them is bound by a contract to protect it.

We'll update this list before we add a new provider that processes personal information.

We also share information when you direct us to, and in a few other cases:

Within CostBook, only the operator can access production systems. That access is used only to provide support you ask for, keep the service secure, or comply with the law.

6. Where your information is stored

CostBook's database and files are hosted by Railway in the United States (Railway's US West region). Emails are processed by Resend in the United States, and payments by Creem, which is based in Estonia in the European Union and whose payment processors operate internationally. CostBook is run from the Philippines, and the operator may access data from there to provide support and keep the service running.

This means your information may be stored or accessed outside the country or province where you live, including outside Canada and Québec. There it may be subject to local laws, which can allow courts and authorities to access it. We stay accountable for your information wherever it is processed. We protect transfers with contracts that require our providers to keep it secure and confidential, including standard contractual clauses where they apply.

7. How long we keep it

Deleting your data. The owner of a business can ask us to delete the business and everything in it, including its activity records. Anyone can ask us to delete their own user account. Email cloyd.abad@costbook.app. We'll confirm the request and delete the data from our live systems within 30 days. Copies in backups are removed as those backups expire on their normal schedule. We may keep a minimal record where the law requires us to, such as billing records, or to show that we handled your request.

8. How we protect it

No system is perfectly secure, but we work to protect your information and fix problems quickly. If a breach affecting your personal information is likely to cause you harm, we'll notify you and the relevant authorities as the law requires. In the Philippines that means the National Privacy Commission, within 72 hours where required.

9. Cookies and browser storage

This website sets no cookies. The CostBook app uses only what it needs to work:

We use no advertising or analytics cookies. Counting visits needs none, and you can switch it off as described in Counting visits to this website; if you do, this website stores that one setting on your device. When you subscribe, Creem's checkout may set its own cookies under its own policy.

Do Not Track and Global Privacy Control: we don't track you across other websites, and we don't let third parties do so on CostBook. If your browser sends either signal, we don't count your visit to this website or to the app.

10. Counting visits to this website

We want to know which pages of this website are useful and which are not, so we count visits ourselves. We don't use Google Analytics or any other third-party analytics, and counting needs no cookies. Here is exactly what happens:

What this does not do: it stores nothing on your device, and records no name, email address or IP address. We don't combine it with your account, and we don't share it with anyone. Visits from search engines and other automated programs are left out.

The CostBook app counts which of its screens are opened in the same way. It records the name of the screen only, never a project, client, quote or any ID in the address, and it doesn't measure time or scrolling.

Your choice: if your browser sends Global Privacy Control or Do Not Track, we don't count you, on this website or in the app. You can also use the "Don't count my visits" link at the bottom of every page of this website. It stores one setting on your device saying you have opted out, which is the only thing this website ever stores there for this, and you can reverse it from the same place.

Why, who sees it and for how long: our legitimate interest in understanding and improving the website and the app. The counts are kept for 400 days, then deleted automatically. Only the operator can see them, in an internal dashboard, and they are hosted by Railway like the rest of CostBook (see Who we share it with).

The location database is IP Geolocation by DB-IP, "IP to Country Lite", licensed under CC BY 4.0.

11. Your rights

Wherever you live, you can ask us to tell you what personal information we hold about you, and to give you a copy, correct it, delete it, or export it. You can also object to how we use it, and withdraw any consent you've given. Email cloyd.abad@costbook.app. You can change most business details and download your data yourself in the app. To change the name or email on your login, email us.

We'll respond within 30 days, and there's no charge. We may need to confirm your identity first. If your information is part of a business account, for example as a team member, we may involve that business's owner. If you received a quote, see section 4.

Philippines

Under the Data Privacy Act of 2012 you have the right to be informed, to access, to object, to erasure or blocking, to damages, to data portability, and to rectification. If you think we have mishandled your information, you can complain to the National Privacy Commission.

Canada and Québec

Under PIPEDA and Québec's privacy law you can access and correct your information and withdraw consent. In Québec, you can also ask for your information in a structured, commonly used technological format, and ask us to stop disseminating it. You can complain to the Office of the Privacy Commissioner of Canada or, in Québec, the Commission d'accès à l'information.

United States

We don't sell or share personal information, or use it for targeted advertising. We honor the access, correction and deletion requests described above wherever you live in the US, and we won't treat you differently for making one.

European Union and United Kingdom

CostBook isn't aimed at the EU or UK, but if those laws apply to you, the legal bases we rely on are listed in section 3. You have the rights described in Articles 15 to 22 of the GDPR. Please raise any concern with us first; you can also complain to your local data protection authority.

12. Children

CostBook is a tool for businesses and isn't meant for anyone under 18. We don't knowingly collect personal information from children. If you believe a child has given us information, tell us and we'll delete it.

13. Changes to this policy

We'll update this policy when the way we handle information changes. If a change is material, we'll email account owners or show a notice in the app before it takes effect. The date at the top shows when this policy was last updated.

14. Data protection officer and contact

Our data protection officer, who is also our privacy officer under Québec law, is Cloyd C. Abad. Write to cloyd.abad@costbook.app, or use the details below:
