A practical place for everyday nail notes

Nail Diary is a small collection of free tools for organising nail-care habits, exploring personal style and understanding the costs you enter. You do not need an account, a subscription or a salon booking to use them. The aim is clarity, not a perfect manicure or a promise about your nails.

What you can do here

• Build an everyday routine around your available time and habits.
• Explore polish shade families without uploading a photograph.
• Keep a dated measurement diary on your own browser.
• Estimate a manicure budget using your own quotes.
• Turn a style preference into a simple nail-art brief.
• Prepare a list of observations to discuss with a professional.

Clear inputs, explainable outputs

Every tool includes a method section. Budget calculations show their assumptions; style suggestions use fixed, written rules; the checklist does not give a diagnosis or a health score. These are organisational aids, not personalised professional advice. You can change your inputs, run the tool again and keep the result as text or a printout.

Privacy by design, with a clear boundary

Tool calculations happen in your browser. No camera, image upload or account system is included. The growth diary saves locally only when you choose it. The Contact form is different: it sends the details you submit to the site administrator. Hosting and other WordPress plugins can have their own logging or cookie behaviour; read the Privacy Policy for that boundary.

Care before claims

Results are general care and style guidance only, not medical advice. Have nail health concerns checked by a qualified professional. Nail Diary does not claim clinical review, endorse a treatment or promise faster growth. Product instructions and professional advice take priority over a generic routine or design idea.
